Professor Kikuchi picked up the small disc in front of him and looked at it carefully.

It doesn't seem to be much different from LD discs just from its appearance, except that it's a lot more compact.

"The biggest difference between it and LD discs is that digital signals are used to restore information in the process of information conversion.

At present, CD technology is still limited to the audio field.

Of course, it has a broader application space in the future, but at present, Shirakawa Electric only needs to focus on the audio field. ”

The so-called digital audio is the use of digital signals to record the waveform of sound.

Before the advent of CD discs, such as vinyl, Walkman tapes, film, etc., were analog audio.

We all know that sound is a wave, and this way of recording and playing back the waveform to physically mimic the original waveform of the sound is analog audio.

Although analog audio has been serving humanity for almost a hundred years since its inception.

However, analog audio also has its drawbacks, such as poor anti-interference ability and noise floor.

Friends who listen to the Walkman have experienced this, and the rustling sound in the background sound is the best proof of this.

In addition, analog audio requires a stylus and a head to restore the signal, so wear and tear is inevitable.

Just like Shirakawa Electric's Obsidian Record Player and Flashman, these two places are the most likely to have problems in terms of service life.

But what really drove the development of CD audio was because analog audio was not suitable for large-scale reproduction and distribution.

Whether it's vinyl records or Walkman tapes, their ripping and transcription are done from a physical level.

And there is a limit to the speed of physical ripping, which also limits the output of vinyl and tape.

In addition, vinyl is not easy to preserve, and tape rewinding is extremely time-consuming, which are the main factors affecting the consumer experience.

Therefore, whether in terms of use demand or large-scale production, the emergence of CD technology is almost inevitable.

Professor Kikuchi put down the CD in front of him and thoughtfully said, "It's an interesting way to store it, but it should be used in a wider range of applications."

Images, texts, images, etc. can be used as a carrier for storage and reproduction.

In addition, perhaps laser technology is the key to its information conversion, and the subsequent decoding is more complicated. ”

"Teacher Kikuchi's eyes are like a torch," Shirakawa Kaede gave a timely slap.

However, he also admired from the bottom of his heart, and the other party could guess the two core problems of CD audio technology just by looking at it.

Tsk, he is worthy of being the person in charge of a national experimental project, and his knowledge reserve in different fields is terrifying.

Professor Kikuchi didn't care about Shirakawa Kaede's praise, he frowned and thought about it.

He picked up the entrustment application materials submitted by Shirakawa Kaede again and went through them.

Just when Shirakawa Kaede thought that there was something wrong, he quickly picked up the pen and began to write and draw on it.

In just five minutes, Professor Kikuchi put down his pen and returned the commissioned materials to Shirakawa Kaede.

"Precision servo technology and digital signal processing technology, Meiji's strength is so-so.

However, with VLSI technology, Meiji is far behind.

So if you want to gain something in this area, you can only think of another way. ”

was commented on by Professor Kikuchi so unsympathetically, and Shirakawa Kaede, Daiji Yamashita, and Hui Yamazaki, who were born in Meiji, were all a little embarrassed.

But they can't refute anything, who made this big guy himself a technical master.

What's more, the other party is not wrong, Meiji University is really good at the field of social sciences and humanities, such as law and business.

"Mr. Kikuchi, then you look at VLSI technology..."Shirakawa Kaede, who had no choice but to be cheeky, could only continue to ask the big guy for guidance.

Meiji didn't have it, so I can't just do it. Shirakawa Electric needs to rely on the foundation of Meiji, but it cannot rely on Meiji.

If you want to base yourself on the future with technology, then you have to do it no matter how difficult it is.

Professor Kikuchi didn't seem surprised by Shirakawa Kaede's cheekiness either, and he lifted his chin.

"Go to Matsumura Masaaki-san of Tokyo Institute of Technology, the contact information has been left to you, and I will say hello too.

As for whether you can move the other party, that's your Shirakawa business. ”

"Mr. Kikuchi, Shirakawa thanks for your care." Shirakawa Kaede, who was a little excited in his heart, bowed convincingly.

Professor Kikuchi waved his hand indifferently, and he was actually quite impressed by this junior.

Where you can, you can also grab it.

As for future achievements, it will be left to time to verify.

Seeing that Professor Kikuchi didn't say anything more, Shirakawa Kaede also said goodbye and left with interest.

To be honest, for being able to know a big guy like Professor Kikuchi, Shirakawa Kaede is very fortunate in his heart.

Only at present, it seems that all the technical problems encountered by Shirakawa Electric ultimately need to be solved more or less through him.

Although Professor Kikuchi did not end up in person, his identity was there.

The personal resources behind him are slightly exposed, and it is enough for Baichuan Electric to go far away.

To be honest, if it weren't for the fear that Professor Kikuchi wouldn't like it, Shirakawa Kaede would have wanted to write an equity transfer letter directly to him.

It's a pity that this kind of bigwig, who has the support of national resources, can't look down on these at all.

Forced delivery, but it is cliché, and you can only wait for the coming day.

Outside the laboratory door, Shirakawa Kaede grabbed Hui Yamazaki again.

"Senior Yamazaki, you must come to Shirakawa Electric more often. Yasuda-san, they miss Senior Yamazaki very much. ”

This Shirakawa Kaede didn't lie, after all, they had worked together happily for half a year, and they still had feelings.

Hui Yamazaki also nodded happily, "Definitely, definitely." Say hello to Yasuda-san on my behalf. ”

"No problem, goodbye Senior Yamazaki."

Waving goodbye, Yamazaki Hui looked at the back of Shirakawa Kaede and their departure, and was silent for a long time.

…

The industry-university-research project with Meiji University has come to an end for the time being.

The specific commission plan has been submitted by Kaede Shirakawa through Professor Kikuchi.

At present, the preliminary budget is for Shirakawa Electric to provide 20 million yen per year.

For Meiji University's professional team, we will conduct targeted research and development on precision servo technology and digital signal processing technology.

As for the target, it is, of course, a CD disc.

Although the CD format has not yet been officially promulgated, in fact, both Philips and Sony have had technical conferences of related products a few years ago.

So it's not difficult to get a CD, and what Shirakawa Kaede wants to do is a CD disc decoding device, a CD player.

Meiji University needs to come up with a concrete decoding design plan in the next two years, and of course the main goal is the circuit design part.

Precision servo technology Shirakawa Electric will also be involved, and the problem should not be big.

The difficulty is still in the digital signal processing part, and it is necessary to come up with a design solution that can be commercialized within three years at the latest.

This is already the longest time limit that Shirakawa Kaede can accept, and the reason why he spent so much money to lay out in advance is not just to be one step ahead.

If this cannot be done, then the so-called industry-university-research will be meaningless.

Shirakawa Kaede knows very well in his heart what kind of formatting competition and what kind of participation in the formulation of standards.

Shirakawa Electric is still far away, and even if he has a shy face, people will not look at him.

Therefore, the road has to be taken step by step, and Shirakawa Electric first engages in a supporting player for CD discs.

When you have enough strength in the future, you can participate in higher-end competition.
