"The disc diameter is 0 mm, the thickness is millimeters, the scanning speed is HN, which is about 500 revolutions per minute for the inner ring of the disc, the outer ring of the disc is 0 revolutions per minute, the reading and writing speed is IX, that is, 150KH, and the capacity is 70UN..."

In Sony's laboratory, Chen Chong was wearing gloves and clamped a piece of plastic sheet that reflected colorful light under the light with his fingers. On the surface, he was listening to a Japanese man's endless explanation, but he was thinking about it.

CD CD

Sony finally took out this thing.

Now it is a cutting-edge high-tech product. It is a powerful tool for music youth in ten years, a pirated weapon for the streets twenty years, and thirty years later... it is only a legendary name left.

It is the starting point of digitalization of audio and video, it is the starting point of large-capacity storage, it is one of the greatest inventions after transistors, and it is an epoch-making technology...

"Mr. Chen, what do you think?"

"It's amazing, this is an invention that fascinates and goes crazy about it." Chen Chong praised Sony's vice president and head of the CD project in English, and said: "I like this thing very much. This is another revolutionary product that Sony invented after Trilon, video recorder, and aIkmau."

“What is its market prospect?”

"Very good, this thing is very useful and has a very broad prospect." Chen Chong used several times in a row and praised: "I admire Sony's scientific research capabilities very much. I think it will give birth to a market worth tens of billions of dollars, no worse than the video tape market."

Oga Nobuo was very satisfied with Shen Chong's attitude and said with a unique Japanese smile: "Mr. Chen, have you used the wrong unit? Is it mn11u instead of nt11uu?"

"No, I'm talking about nt11." Chen Chong also laughed. He put down the CD and asked, "Mr. Oga, what field does Sony intend to apply this technology?"

"Of course it's the music market." Oga Dieno said very proudly: "The CD that Shen Jun saw just now is called the digital music CD. It was jointly developed by our Sony and Philips in the Netherlands. Sony's CHP Polykin is one of the five major music companies in the world. The two companies have joined forces to promote this new music storage and broadcast format. I believe it will be successful. The vinyl record is too large, it is inconvenient to carry, and there will be losses during playback. Using this latest and most advanced laser reading technology to create music records will never get worn, and the sound quality will always be the same as when recording."

Chen Chong was secretly happy when he heard this.

It seems that Sony and Philips have not realized the real potential of CDs, and they only plan to replace traditional vinyl records. However, they did not expect that this thing can also be used as a computer storage device. However, it is no wonder that in 19RU, the memory was still in K units, and the hard disk was only a few 44NR disks, and the 70UN CD was too big for the computer, as if a child was holding a giant sword...

CD is something that Sony and Philips jointly developed for several years before they were developed. The technology was basically taken in 19RU. Just two days before Shen Chong came to Japan, the two companies had jointly released the red book on CD technology. Therefore, he couldn't get the profitable market of music CD. You should know that after the invention of CD, any music company needed to purchase authorization from Philips and Sony when making CDs. Before Shen Chong traveled through time, the CD market had shrunk to an extreme, but the licensing fee was still as high as 50UU US dollars per set. From this, you can imagine how much money Philips and Sony made on CDs in the years before the rise of NP3.

But getting up early and rushing for late trading is a common tragedy in the history of technology. Sony and Philips focus on the music market, and when they have the chance to send a chance to grab the computer CD market, because the CDs used for music and CDs used for computers are both CDs, but the formats of data compression and storage are not the same. The use and market of CDs used for CDs are much broader than that of a single music market.

However, CDs used for computers still need to wait for IHN to make a breakthrough and the personal computer market exploded before they can get started. Now? This CD has other uses for Shen Chong - digital storage of movie sound effects.

In the era of film films, almost all stereo sound effects of movies, whether Dolby's A or Sony's P, were recorded between the tooth holes of movie films, with only one exception, that is, the DTDT that Spielberg fiddled with when filming "Jurassic Park" was burned on the CD, and then used the supporting machine to play simultaneously during the movie screening.

The storage space on the film is limited, and when recording the sound effects, a large compression ratio is required, so the sound effects are not particularly outstanding. DT uses CDs as storage medium, with large capacity, good sound quality, and good scalability. It can also be used in the era of D and digital films. There is also a great advantage, that is, when screening in different countries, you only need to change the CD, and there is no need to reprint the dubbed version of the movie copy, which can save a lot of costs.

So the DT model is a digital film sound development plan that Chen Chong chose early in the morning. Now that the CD has come out, he can start it with all his strength in the film technology laboratory in the United States.

"Mr. Oga, I just heard from the technician that this new CD 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 about 70 minutes. I guess it is the capacity used to formulate it?"

"Mr. Chen is worthy of being a musical genius who wrote "That Flower" for Ms. Momoe Yamaguchi." Oga Nobuo Ichi's expression of meeting a confidant, saying: "Philips originally planned to make a 115mm disc with a playback time of UU minutes, but I think that to bring the best enjoyment to music lovers, they cannot interrupt them during listening to music, which will destroy the atmosphere of the music. So I insist on increasing the capacity and being able to play the complete Beethoven Ninth Symphony. The longest Ninth Symphony in the world is the 1951 version conducted by the famous conductor Ford Wangerle, which lasts 74 minutes, so I increased the disc to 0 mm and the playback time was 74 minutes."

"Mr. Oga is a fan of classical music. It is really well-deserved. I think your efforts will definitely be understood and grateful by all music lovers all over the world." Chen Chong used the memes he saw on the Internet in his previous life to touch Oga Nobuo's G-spot, and then asked: "I don't know when this new technology will be officially commercialized?"

"We have just completed the technical work now, and we have only made some prototypes, and it will take some time to wait for mass production."

"Mr. Oga." Chen Chong said with an expression that was urgently unanswered, "I wonder if I can own a prototype? You know, I am also a music enthusiast. The audition just now shocked me. I really hope to own it sooner."
