  • History of the Compact Disc Starting in the mid 1980's, compact discs (CD) began to take over both the audio and computer program market. Much of this can be attributed to a general acceptance of certain specifications regarding compact discs, known as the "Color Books." Originally designed and developed by both Sony and Phillips, the concept of the Color Books was patented and standards were developed. These are a collection of five books that describe the specifications and standards CD technology follows. This led eventually to the current audio CD technology (Figure 1).
  • The first book, written in 1980, was named the "Red Book" and outlined the specifications regarding CD Digital Audio. This was the common CD used in stereo systems, and was capable of holding up to 99 tracks, for a total of roughly 74 minutes of audio information.
  • The second book was written in 1983 and is known as the "Yellow Book", comprising the basis of the Compact Disc - Read Only Memory (CD-ROM). This became the standard for computer-based compact discs, and meant that any computer system that had a CD-ROM drive, could read this format. It is capable of holding around 650 million bytes of data. CD-R's were developed under the same standards, but the actual CDs were comprised of different material. While the generic CD-ROM discs uses aluminum in their construction, the CD-R discs uses gold, which makes color a distinguishing feature.

  • The third book, known as the "Green Book," covered CD-Interactive technology, is used to synchronize both audio and data tracks on a CD-ROM in order to provide things such as full motion video combined with interactivity. Published in 1986, Phillips Interactive primarily marketed this technology.
  • The fourth, the "Orange Book", is merely an outline for the coming generation of writable CD technology, primarily CD-E. (Compact Disc - Erasable) This is meant to replace, or be used in the same matter as floppy discs, only providing a much larger medium to store data. The technology is available today, but know otherwise as CD-RW. (Compact Disc - ReWritable) Much like a floppy disc or hard drive, data can be written and rewritten to these discs, allowing for a very large yet portable medium of data storage.
  • The last book known as the "White Book," is a plan for the future of compact disc technology. It outlines what is known as video compact discs, and contains the standard of data compression that is used to display large amounts of audio and video on a home computer. This concept more or less morphed into what is now known as DVD (Digital Video Drives,) a technology produced primarily by Sony, Phillips and Toshiba. While not compatible with the standard CD-ROM drives used in computers, it did achieve what the White Book had outlined for the future.
  • While an overview of how compact disc technology developed and became so popular is presented, it fails to explain how the technology works. There are, however, relatively simple processes accounting for how a compact disc is read and how the CD-ROM drive translates that into data your computer can understand. First is the construction of the compact disc. It is built from a layer of polycarbonate plastic, covered in a color-dyed layer of aluminum, and followed by a protective layer of lacquer. Figure 2 shows a cross section of a compact disc, illustrating the different layers and providing a general idea behind its construction.
  • When a compact disc is written to, tiny rivets are made in the surface of the disc called stripes or pits. The areas between these pits are called lands, which together make up a pattern where data is written. From there, a CD-ROM drive uses a read head to interpret these patterns, which is done by focusing a laser beam on the surface of the disc. While the CD is spinning, this laser comes in contact with the lands and pits. If the laser comes in contact with a pit, the light is reflected off in all directions. However, if the light comes in contact with a land, it reflects back into the read head, triggering an electric impulse. Figure 3 illustrates the difference between a land and a pit, and how the light is reflected in each situation.
  • A pattern is developed from these electric impulses, and the CD-ROM drive returns this pattern to the computer as a string of 1s and 0s. This binary or digital data is in turn interpreted by the software controlling the CD-ROM drive, and then translated into something the computer can use, be it an executable program, an image, or a sound file.

  • James Russell invented the compact disc in 1965. James Russell was granted a total of 22 patents for various elements of his compact disc system. However, the compact disk did not become popular until it was mass manufactured by Philips in 1980.             The first working prototype was produced in 1979. At the time of the technology's introduction it had more capacity than computer hard drives common at the time. The reverse is now true, with hard drives far exceeding the capacity of CDs.
  • n 1979, Philips and Sony got together to manufacture the compact disc.
  • The team leaders of this project were Kees Immink and Toshitada Doi. Philps handled the manufacturing process along with the Eight-to-Fourteen Modulation (EFM), while Sony too care of the error connection method, better known as CIRC. However, Philips claims that this invention was not a one man's job but a collective contribution by members of both the companies who worked together as a team.

  • Audio CDs and audio CD players have been commercially available since October 1982.            Mass adoption didn't happen immediately -- CDs wouldn't overtake cassette tapes until the late 1980s. The first album to sell 1 million copies in the CD format and outsell its vinyl version was Dire Straits' "Brothers in Arms," released in 1985.
  • This disc was taken over by nearly all markets across the globe, especially the Europe and the United States consumer market. The first successful CD to be launched was Brothers in Arms in 1985.A compact disc (CD) is a popular form of digital storage media used for computer files, pictures, and music. The plastic platter is read and written to by a laser in a CD drive. It comes in several varieties including CD-ROM, CD-R, and CD-RW.  As with most new technologies, one reason for the slow spread of CDs was their steep price tags. The Sony CDP-101 player sold for the equivalent of $730 when it first hit Japanese shelves in 1982. Accounting for inflation, that's about $1,750 today. The audio CDs themselves were $15, which is $35 in 2012 dollars.
  • Standard CDs have a diameter of 120 millimeters (4.7 in) and can hold up to 80 minutes of uncompressed audio or 700 MB (actually about 703 MB or 737 MB) of data. The Mini CD has various diameters ranging from 60 to 80 millimeters (2.4 to 3.1 in); they are sometimes used for CD singles, storing up to 24 minutes of audio or delivering device drivers.

  • It was Philips Industries, a Dutch-based electronics giant (known in the music world as owner of the PolyGram labels), that made the first announcement, on May 17, 1978. Working with Japan's Sony Corporation, Philips announced that they would have a marketable compact disc and appropriate hardware ready "in the early 1980s." That promise was kept on October 1, 1982, when the compact disc was introduced in Japan by CBS/Sony, with 112 different CD titles and a CD player (Sony's CDP-101). The last few months of 1982 were hectic, with Sony selling over 20,000 CD players and Hitachi also posting sales in the 6,000 per month range for their player. Prices for these initial players ran from about $700 to about $1000. The discs themselves, priced at about $15-20, could not be pressed fast enough to meet demand. Sony's research on who was buying the discs in Japan indicated it was young (20s, early 30s) men with a particular interest in sound quality. Perhaps it was this research that led others to believe, as the rest of the world looked on in curiosity to what was happening in Japan, that CDs would fill a niche for high quality sound enthusiasts and little else. By the end of 1982, CBS/Sony and Epic/Sony had issued 122 CD titles.
  • The stories about compact discs published in Billboard during early 1983 are fascinating. The lead story on January 29 has PolyGram mulling over how to package the CD in the US when it's released later in 1983, leaning toward the (in retrospect, ill-fated) "long box," the 6"x12" cardboard box which they convinced the industry to adopt at the RIAA (Record Industry Association of America) meeting the next week. (Many at the meeting were considering a 12"x12" box!)
  • In February, Sony announced a "firm" suggested retail price of $1000 for their CD player and $16.98 for discs when they would be introduced later that year in the US. February 23, 1983 marked the debut of the compact disc in Europe, with PolyGram's Hans Gout noting that, "The sooner the Compact Disc replaces the conventional black vinyl LP, the better." By early March, Sony and CBS Records in the US were supplying free compact disc players and discs to selected radio stations here, mostly with Classical and Album-Oriented Rock formats. The March 12 issue of Billboard also notes that Capitol Record Shop, a Hartford, Connecticut, record store, had begun importing CDs from Japan and Europe, with 24 titles at a price tag of $24.95 each. At the time the owner was interviewed, he had only sold a total of one disc.
  • ...3 more annotations...
  • Several months of delays and anticipation dragged by, until in late June, 1983, CBS finally shipped the first CD "prepacks" to a select 35 accounts. Each prepack had a total of 12 titles, with no more than a total of 1000 prepacks altogether in the first shipment. Among the individual titles were Pink Floyd's Wish You Were Here, Billy Joel's The Stranger, Michael Jackson's Thriller, and Toto's Toto IV. Other titles were jazz and classical. The CD era had begun in the United States.
  • Within about a month, CBS had issued several other pop/rock titles, including Boston's Don't Look Back, Earth Wind & Fire's Raise!, ELO's Discovery, Journey's Escape, Boz Scaggs' Silk Degrees, Barbra Streisand's Guilty, and Bruce Springsteen's Born To Run. These had the CBS logo (and mastering numbers in the DIDP 50000 series). Later, these were reissued with Columbia logos, but these remain as examples of the earliest American CD releases
  • After the introduction of the CD here, most of the stories in the trade press center around the acute shortage of pressing plants. At that time, there were two major plants, PolyGram's Hanover, West Germany plant, and Sony's plant in Japan. (Almost all the CDs sold under US labels for the first few years were either made in Japan or West Germany.) Sales figures for the US in 1983 totalled about 30,000 players and 800,000 discs. Still, no one really knew if the CD would succeed.

      Jul 28, 2000 8:37 PM-James Russell thought of it in 1965 while working for Pacific Northwest National Laboratory, operated by Battelle Memorial Institute for the U. S. Department of Energy. His idea, known as Optical Digital Recording (ODR), was to store information digitally on photosensitive film using a laser to record and to play back. In 1974, for his work on ODR, Russell was honored with an R&D 100 Award. By 1980 he had made the first disk player.
  • For a long time Battelle was unable to interest anyone else in ODR. Eventually Sony and Philips licensed it, established a proprietary ODR format for audio called “Compact Disc” (CD), and delivered a commercial product in 1982, followed in 1985 with a related ODR format for data called CD-ROM. Sony and Philips call these their “inventions”, misleading many into seeing Sony and Philips as visionary. They are often given sole credit for this revolutionary technology. In actuality, their contribution was to bring Russell’s system to market, and only after taking two decades to recognize its value.
  • As you might expect, Sony and Philips have made millions, and Russell himself got nothing.

  • The Puget Sound Engineering Council selected Russell as the 2005 Industry Engineer of the Year. And despite all of his accomplishments, it wasn't until Joe Decuir of Seattle's chapter of the Institute of Electrical and Electronics Engineers, Inc., (IEEE) saw a story about Russell in the local newspaper that he suggested Russell's name to the committee last fall.
  • In the mid 1950s, he was frustrated with the sound quality of LPs, which started wearing out after only a dozen plays. He even tried using a cactus needle to play records because the jewel needle wore out the vinyl faster and didn't sound as clear. Russell wanted a way to capture the complexity and nuances of classical music without damaging the recording. And the idea that sparked a multi-billion dollar industry was about to take shape in Russell's mind.
  • In fifth grade, he started building radios out of parts he scrounged from the neighbors. In high school, he took a job setting up a commercial radio station, even though he didn't know how to hook up most of the equipment. "But I learned– rapidly,” he laughs.
  • ...12 more annotations...
  • After graduating from Reed College with a degree in physics in 1953, Russell took a job with General Electric in the Hanford Nuclear Plant doing experimental work.
  • Battelle took over the Hanford Laboratories in 1965 and gave Russell a lab and time to work on some of his imaginings, including the crazy idea that sound could be converted to strings of numbers and reproduced using light.
  • He had come up with a way of using a laser to read digital bits of information, which later became the most widely-used way to read just about everything. By using a light to read the data, the record would never wear out. The data are encoded as microscopic pit marks on the surface of the disk, which, when spun, can be read to reproduce high-quality sound.
  • The original goal was to record television shows, not music, because adding visuals would be more difficult. If television couldn't be recorded digitally, Russell and his backers decided they would at least know where they stood. In 1973, they were successful, but they were ahead of their time. Amazingly, no one wanted to buy a license for the precursor to the DVD.
  • By 1991, about 25 years after he came up with the idea, CDs were outselling their predecessors, audio tapes, in record stores nationwide.
  • But all he can do is shrug ruefully, "I didn't invent the CD, I invented the technology.”
  • Today, Russell has more than 50 patents to his name. He continues his work from the basement of his Bellevue home where he and Barbara have lived for more than a decade.
  • The first devices were called Optical Digital Data Storage –the term CD is actually a trademark of Philips. The original storage units were made of glass plates, about the size of large index cards, which could be read as a laser scanned over them.

  • Compact Disk of James Russel The first workable digital compact disc device, the precursor on now ubiquitous CD/DVDs, was invented in the late 1960s by the American physicist James Russell
  • James T. Russell was born in Bremerton, Washington in 1931. He was always a smart boy and at the age of six he devised a remote-control battleship with a storage compartment for his lunch (obviously the young James enjoyed the food :-)
  • In 1953, Russell earned his Bachelor degree in physics and graduated from Reed College in Portland. Afterwards he went to work as a Physicist in General Electric's nearby labs in Richland, where his wife Barbara worked as a chemist. At GE, working for the Hanford Nuclear Plant, and appointed as a "designated problem-solver" for GE experimental unit, Russell initiated many experimental instrumentation projects. He was among the first to use a color TV screen and keyboard as the main interface between computer and operator. He also designed and built the first electron beam welder. In 1950s and early 1960s, Russell, who was an avid music listener (he was found of classical music—Beethoven, Chopin, Mussorgsky, Offenbach. etc.), quite frustrated with the wear and tear of his vinyl records and their poor sound quality, tried to improve the record player. Initially he tried using a cactus needle, instead of steel one, for a stylus, but with no success. "After each record you had to resharpen the needle," he recalled.
  • ...6 more annotations...
  • In 1965, the Ohio-based Battelle Memorial Institute opened its Pacific Northwest Laboratory in Richland, to took over management of Hanford's lab, and James Russell joined the effort as Senior Scientist. Thus he gained an audience for his more far-fetched ideas and immediately began to pepper Battelle with proposals for new commercial concepts. The optical digital technology was initially met with skepticism, as it was not believed that one could digitize sound. "Here I was at Battelle, enmeshed in the scientific community, and one of the first things I had to demonstrate was that you could digitize music and reproduce it" he said. "Music into numbers? Come on now, Russell."
  • ple to convert into an audible or visible transmission.
  • Through the 1970s, Russell continued to refine the CD-ROM, adapting it to any form of data. However, like many ideas far ahead of their time, the CD-ROM found few interested investors at first. In 1971, Eli S. Jacobs, a New York venture capitalist, pioneered the commercialization by forming Digital Recording Corporation to further enhance the product for the consumer video market, and hired Russell and a team of technicians to come up with a video disk. Their efforts led to a 20-minute video disc in 1973.
  • "The vision I had in mind was of television programs on little plastic records. The networks, instead of putting programs on television, would print records. And if you wanted to watch your favorite programs you'd get them in the mail and put in the disk whenever you want," Russell said. "Jacobs thought, if we can do it, hey great, we've got the whole world by the tail. And if we can't, well at least you know where you are." In 1974 Digital Recording Corporation announced an optical digital television recording and playback machine, the first device to digitize a color image, at a Chicago trade show. The response from large potential investors was rather cool. Philips Electronics representatives visited Russell's Battelle lab in the summer of 1975, and they discounted the entire premise of his work. "They said: It's all very well for data storage, but you can't do that for video or audio." recalled Russell. Philips had just released its laser disc, an analog optical video player, and they were convinced that analog was the only way. "Philips put $60 million into development of the laser disc. We were advised that nobody would tell them they had made a mistake."
  • Sony launched its CDP-101—the first commercialized CD player in 1982. Sony and Philips paid royalties from CD player sales to Battelle and to Optical Recording Corporation. Time-Warner and other disc manufacturers settled with the Optical Recording Corporation in 1992, paying $30 million for patent infringement. The court determined that Optical Recording had the sole rights over the technology mentioned in the patents. But because the patents properly belonged to Russell's employer, he never got a cent out of either deal. By 1985, Russell had earned 26 patents for CD-ROM technology. He then founded his own consulting firm, where he has continued to create and patent improvements in optical storage systems, along with bar code scanners, liquid crystal shutters, and other industrial optical instruments. His most revolutionary recent invention is a high-speed optical data recorder and player that has no moving parts. Russell earned another 11 patents for this "Optical Random Access Memory" device.

  • James T. Russell James T. Russell (Left), born in Bremerton Washington, is a very influential inventor in the music industry. Russell, an avid music fan, frustrated by the poor quality of his records, set out to create a means of playing music that would have better longevity. With this goal in mind, Russell created the first “digital-to-optical recording and playback system,” what we know now as the compact disc. He used light to read the product instead of actually touching the material. The invention was finished in the late 1960s, and was originally patented by 1970. By 1985, Russell had over 26 patents on the invention, and sold the licenses to companies like Phillips Electronics, to produce the compact disc.
  • The music industry has been changed and has had great advancements throughout history. One of the main forms of advancement stems from the ways in which the industry has faced recording, and publication. Society has seen the industry veer from the standard eight-track, to the record, to the tape, to CD, to MP3, etc., and with each new advancement, the entire industry changes. It isn’t uncommon for a person to see many changes of medium within a lifetime. With each change comes better quality, more innovation, and more possibility for further progression.
  • The Compact Disc The invention of the CD has had one of the most influential, and timely effects on the music industry. The CD came into the technology scene in the 1980s. Philips Electronics N.V first produced it in 1980. The invention originated in the computer industry in 1980, and took over the floppy disk. It could contain the same amount of information as 1,000 floppy disks, thus it became a very popular alternative. Soon, it also became influential in the music industry in 1982, when technology was invented that allowed the disc to hold audio files with a far better sound quality than was prior possible. The compact disc is read by a laser beam, which leads to a more accurate and qualified playback. In addition, compact discs allowed the user to skip between songs with out using the fast forward/ rewind button, a feature that wasn’t available on the magnetic cassette tape.
