In Sony's lab, Shen Chong wore gloves and held a plastic sheet of colorful light reflected in the light between his fingers, listening intently to the chatter of a Japanese man, but his heart was cranky. Pen & Fun & Pavilion www.biquge.info
cd, ah, cd
Sony finally got this thing out.
Now it is a high-tech cutting-edge product, ten years later, it will be a weapon for music youth, twenty years later, it will be a piracy weapon on the bad street, and thirty years later...... Thirty years later, it was left with only a legendary name.
It is the starting point of audio-visual digitization, it is the starting point of mass 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 an invention that fascinates and drives people crazy." Shen Chong complimented Sony's vice president and head of the CD project in English, Norio Ohga, saying: "I like this thing very, very much, this is another revolutionary product invented by Sony after Trilon, VCR, and AIKMAU." ”
"And what is its market prospects?"
"Very good, this thing is very useful and very promising." Shen Chong used several in a row and praised: "I admire Sony's scientific research capabilities very much, and I think it will give birth to a market worth tens of billions of dollars, no worse than the videotape market." ”
Norio Ohga was very satisfied with Shen Chong's attitude, and said with a smile unique to the Japanese: "Mr. Shen, did you use the wrong unit, is it mn11u instead of nt11uu?" ”
"No, I'm talking about NT11" Shen Chong also smiled, he put down the disc, and asked: "Mr. Oga, what field does Sony plan to use this technology in?" ”
"The music market, of course." He Norio said very complacently: "Shen Jun just saw the CD, the full name is digital music CD, we Sony and the Netherlands' Philips company jointly developed, Sony's CH Pu's Polygram, are one of the world's five major music companies, the two companies have joined forces to promote this new music storage and broadcast format, I believe it will be successful, vinyl records are too big, inconvenient to carry, and there will be loss when playing, with the latest and most advanced laser reading technology to make music records, there will never be wear and tear, The sound quality will always be the same as when you recorded it. ”
Shen Chong was secretly happy when he heard this.
It seems that Sony and Philips have not yet realized the true potential of the CD, and only plan to use it to replace the traditional vinyl record, but they did not think of this thing, which can also be used as a storage device for the computer, but it is no wonder that in 19ru, the memory is still in k, and the hard disk is only a few 44nr disks are very luxurious, and the 70un disc, for the computer, is too big, as if a child is holding a giant sword as incongruous...
CD is Sony and Philips jointly engaged in several years to study something, in 19ru technology has been basically formed, just two days before Shen Chong came to Japan, the two companies have jointly released the red book of CD technology, so the lucrative market of music CD, he can't eat, you must know that after the invention of CD, any music company needs to buy licenses from Philips and Sony when making CD, before Shen Chong crossed, the CD market has shrunk into shape, But licensing fees are still as high as $50UU, so imagine how much money Philips and Sony made on CDs in the years before NP3 came to life.
But getting up early in the morning and catching up with a late set is a common tragedy in the history of science and technology, Sony and Philips focus on the music market, Shen Chong has the opportunity to come first, to grab the computer disc market, because music CDs and computer CDs, although they are CDs, but the format of data compression and storage is not the same, CDRON uses and markets, can be much broader than a single music market.
However, the CD for computers still needs to wait for IHN to exert force, and after the explosive development of the personal computer market, there will be a start, now? For Shen Chong, this CD has other uses - digital storage of movie sounds.
In the era of film films, almost all movie stereo effects, whether Dolby's A or Sony's P, were recorded between the perforations of the film film, with one exception, that is, Spielberg's DTDT tinkered with during the filming of "Jurassic Park" was additionally burned on a CD, and then used a companion machine to play it simultaneously during the film.
The storage space on the film is limited, and the sound effect is recorded on it, which requires a large compression ratio, so the sound effect is not particularly excellent, and DT uses CD as a storage medium, with large capacity, good sound quality, and good scalability, in the era of D and digital cinema, it can also be used, and there is also a great advantage, that is, when it is screened in different countries, it only needs to replace the CD, and there is no need to reprint the dubbed version of the film copy, which can save a lot of costs.
Therefore, the DT mode is a digital film sound development plan that Shen Chong has chosen early on, and now that the CD is out, then he can go all out in the film technology laboratory in the United States.
"Mr. Oga, I just listened to the introduction of the technician, saying that this new type of CD-ROM has a capacity of 700 and can play music for about 75 minutes, if I remember correctly, the longest music in the world is Beethoven's Ninth Symphony, which is probably more than 70 minutes, so it must be based on this capacity?"
"Mr. Shen is worthy of being a musical genius who wrote "That Flower" for Miss Momoe Yamaguchi" Norio Ohga said with an expression of meeting a confidant: "Philips originally planned to make an L15mm disc with a playback time of UU minutes, but I thought that in order to bring the best enjoyment to music lovers, we should not let them be interrupted in the process of listening to music, which would ruin the atmosphere of the music, so I insisted on increasing the capacity and making sure that I could play the full Beethoven Ninth Symphony. The world's longest Symphony No. 9 is a 195l version conducted by the famous conductor Ford Wangele, which is 74 minutes long, so I increased the disc to 0 mm and set the playing time at 74 minutes and seconds. ”
"Mr. Oga is a lover of classical music, and I think you will be understood and appreciated by all music lovers around the world." Shen Chong used the stalk he saw on the Internet in his previous life to touch the G-spot of Norio Ohga, and then asked: "I don't know when this new technology will be officially commercialized?" ”
"We've only just finished working on the technical side of things, we've only made a few prototypes, and we're still going to have to wait for mass production."
"Mr. Oga." Shen Chong had an expression of impatience and said, "I don't know if I can have a prototype?" You know, I'm also a music enthusiast, and I was blown away by the audition, and I wish I had it sooner. ”
Shen Chong is Sony's largest private shareholder, and the laser record technology is very advanced, and Oga Norio is very confident, so he is not guarded, he said with a smile: "Of course, having a musical genius like Mr. Shen to help test is also an affirmation and encouragement for our work." ”
