    "The diameter of the disc is 0 mm, the thickness is mm, the scanning speed is HN, which is approximately equal to 500 revolutions per minute of the inner ring of the disc, and 0 revolutions per minute of the outer ring of the disc. The read and write speed is IX, which is 150KH, and the capacity is 70UN"  In Sony's laboratory, Shen Chong wore gloves and held a piece of plastic sheet that reflected colorful light under the light between his fingers. On the surface, he was listening intently to a Japanese man's explanation, but in his heart he was thinking wildly.  CD ah CD Sony finally took this thing out.  Now it is a cutting-edge high-tech product, ten years later it will be a tool for young musicians to show off, twenty years later it will be a tool for piracy in the bad streets, thirty years later Thirty years later it will only have a legendary name.  It is the starting point of audio and video digitization, it is the starting point of large-capacity storage, it is one of the greatest inventions after the transistor, it is an epoch-making technology "Mr. Shen, what do you think?" "It's amazing, it's fascinating.  , and was crazy about the invention.¡± Shen Chong complimented Norio Oga, the vice president of Sony and the person in charge of the CD project, in English, saying: ¡°I like this thing very, very much. This is Sony¡¯s successor to Trinitron, video recorder, and aIkmau.  After that, another revolutionary product was invented. "What is its market prospect?" "Very good, this thing is very useful and has great prospects." Shen Chong used several in succession and praised Sony's scientific research capabilities.  I admire it very much. I think it will create a market worth tens of billions of dollars, no less than the video tape market." Norio Ohga was very satisfied with Shen Chong's attitude and said with a unique Japanese smile: "Mr. Shen, you.  Did you use the wrong unit? "Mn11u instead of nt11uu?" "No, I'm talking about nt11." Shen Chong also laughed. He put down the disc and asked: "Mr. Dahe, what are Sony planning to use this technology for?"  Field? " "Of course it's the music market." Norio Ohga said very proudly: "The CD that Shen Jun just saw is called digital music CD. It was jointly developed by Sony and the Dutch company Philips. It is produced by Sony's CH Pu.  PolyGram is one of the top five music companies in the world. The two companies have joined forces to promote this new music storage and playback format. I believe it will be successful. Vinyl records are too big, inconvenient to carry, and will be cumbersome when played.  There will be no wear and tear, but using this latest and most advanced laser reading technology to make music records will never wear out, and the sound quality will always be the same as when it was recorded." Shen Chong was secretly happy when he heard this.  It seems that both Sony and Philips have not realized the true potential of CD. They only planned to use it to replace traditional vinyl records, but they did not expect that this thing could also be used as a storage device for computers. But it is no wonder that in 19RU, memory  In K, the hard drive only has a few 44NR disks, which are very luxurious. The 70UN optical disk is too big for the computer, as uncoordinated as a child holding a giant sword CD was jointly developed by Sony and Philips for several years.  What was just developed, the technology had basically taken shape in 19RU. Just two days before Shen Chong came to Japan, the two companies had jointly released a red book on CD technology. Therefore, he was eating into the lucrative market of music CDs.  No, you have to know that after the invention of CD, any music company needs to purchase licenses from Philips and Sony when producing CDs. Before Shen Chong traveled through the world, the CD market had shrunk terribly, but the licensing fee was still as high as 50UU US dollars.  A set, from which you can imagine how much money Philips and Sony made from CDs in the years before the rise of NP3.  But getting up early and catching up late is a common tragedy in the history of technology. Sony and Philips focus on the music market, and Shen Chong has the opportunity to be the first to arrive and grab the computer CD market, because music CDs and computers  Although the CDs used are all CDs, the data compression and storage formats are different. The uses and market of CDRON are much broader than the single music market. ?????????????????? However, CDs for computers still need to wait for IHN¡¯s efforts. After the explosive development of the personal computer market, they will start to take off. Now?  This CD has another use for Shen Chong - digital storage of movie sound effects.  In the era of film movies, almost all movie stereo sound effects, whether Dolby A or Sony P, were recorded between the perforations of the film. There was only one exception, and that was when Spielberg was filming "Jura".  The DTDT that was tinkered with during "The Park" was separately burned on a CD, and then used a matching machine to play it simultaneously during the movie screening.  The storage space on film is limited, and sound effects are recorded on it, which requires a large compression ratio, so the sound effects are not particularly good. DT uses CD as the storage medium, which has large capacity, good sound quality, and good scalability. In D and  In the era of digital movies, it can also be used. Another big advantage is that when showing it in different countries, you only need to change the CD and do not need to re-print the dubbed version of the movie copy, which can save a lot of costs.  So the DT mode is the digital film sound development plan that Shen Chong chose early on. Now that the CD is out, his film technology laboratory in the United States can start it at full speed.    "Mr. Dahe, I just heard the introduction from the technical staff that this new type of CD has a capacity of 700 and can play about 75 minutes of music. If I remember correctly, the longest music in the world is Beethoven's No. 1  Nine symphonies, about 70 minutes, must be based on this capacity? " "Mr. Shen is worthy of being the musical genius who wrote "That Flower" for Miss Yamaguchi Momoe." Norio Ohga looked like he had met his confidant.  Expression, said: "Philips initially planned to manufacture 15 mm discs with a playback time of UU minutes, but I think that in order to bring the best enjoyment to music lovers, they cannot be interrupted while listening to music.  That would ruin the atmosphere of the music, so I insisted on increasing the capacity to be able to play the complete Ninth Symphony of Beethoven. The longest Ninth Symphony in the world is the version conducted by the famous conductor Ford Wangler in 1951.  , up to 74 minutes, so I increased the disc size to 0mm and set the playback time to 74 minutes and seconds. " "I have heard for a long time that Mr. Dahe is a lover of classical music. He is really well-deserved. I think you must have worked so hard.  I will get the understanding and gratitude of all music lovers around the world." Shen Chong used the memes he saw on the Internet in his previous life to touch Norio Ohga's G-spot, and then asked: "I don't know when this new technology will be available.  "Formal commercial use?" "We have just completed the technical work and have only produced some prototypes. It will take some time for mass production." "Mr. Dahe," Shen Chong said with an impatient expression.  I wonder if I can own a prototype? You know, I am also a music enthusiast. I was very shocked by the audition just now. I really hope to own it as soon as possible. " Shen Chong is Sony's largest private shareholder, plus CD.  The technology is very advanced, and Norio Ohga is very confident, so he is not defensive. He smiles and says: "Of course, having a musical genius like Mr. Shen to help with testing is also an affirmation and encouragement for our work."
