Reborn Tokyo Golden Age

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

Only from the appearance, it seems that there is not much difference from the LD disc, except that it is much smaller.

"The biggest difference between it and LD disc is that it uses digital signal to restore information in the process of information conversion.

The current CD technology is limited to the audio field.

Of course, it will have a wider application space in the future, but at present, Baichuan 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 appearance of CD discs, such as the current vinyl, Walkman tapes, films, etc., were all analog audio.

We all know that sound is a kind of wave. This method of recording and replaying the waveform to imitate the original waveform of the sound at the physical level is analog audio.

Although analog audio has been serving mankind for nearly a hundred years since its appearance.

But analog audio also has its defects, such as poor anti-interference ability and low noise.

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

In addition, because analog audio requires stylus and magnetic heads to restore the signal, wear and tear is inevitable.

Just like Shirakawa Electric's obsidian record player and flashman, in terms of service life, these two places are most prone to problems.

But what really drove the development of CD audio was that analog audio was not suitable for mass reproduction and distribution.

Whether it's vinyl records or Walkman tapes, they are ripped and transcribed physically.

The speed of physical dubbing is limited, which also limits the output of vinyl and tape.

In addition, vinyl is not easy to preserve, and tape rewinding takes a long time, which are the main factors affecting the experience of consumers.

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

Professor Kikuchi put down the CD in front of him and thought, "This is a very interesting storage method, but its application fields should be wider.

Images, text, video, 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 Judi's eyes are as bright as torches." Bai Chuanfeng gave a timely flattery.

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

Tsk, you are indeed the person in charge of a national experimental project, and your knowledge reserves in different fields are frighteningly high.

Professor Kikuchi didn't pay attention to Bai Chuanfeng's praise, instead he frowned and thought.

He picked up the entrustment application materials submitted by Bai Chuanfeng again, and went through it.

Just when Bai Chuanfeng thought there was something wrong, he quickly picked up a pen and began to write and draw on it.

Within five minutes, Professor Kikuchi put down his pen, and he returned the entrusted materials to Bai Chuanfeng.

"Meiji's strength in precision servo technology and digital signal processing technology is so-so.

But VLSI technology, Meiji is far behind.

So if you want to gain something in this area, you can only think of other ways. "

Professor Kikuchi made such an unkind comment, and Shirakawa Kaede, Yamashita Daiji, and Yamazaki Ai, who were born in the Meiji era, were a little embarrassed.

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

More importantly, the other party was right. Meiji University is really good at the social and humanities departments, such as law and business.

"Mr. Kikuchi, look at VLSI technology..." Bai Chuanfeng, who had no choice but to be cheeky, could only continue to ask the boss for advice.

Meiji didn't have it, so we couldn't just stop doing it. Shirakawa Electric needs to rely on the background of Meiji, but it cannot rely on Meiji.

If you want to gain a foothold in the future with technology, you have to do it no matter how difficult it is.

Professor Kikuchi didn't seem surprised by Bai Chuanfeng's thick skin, he raised his chin.

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

As for whether you can persuade the other party, that's up to you, Bai Chuan. "

"Teacher Judi, Bai Chuan has been taken care of by you." The excited Bai Chuanfeng bowed in admiration.

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

Where you can, you can also help grab a hand.

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

Seeing that Professor Kikuchi stopped talking, Bai Chuanfeng also took his leave and left.

To be honest, Bai Chuanfeng was very fortunate to know such a boss as Professor Kikuchi.

From the current point of view, all the technical problems encountered by Baichuan Electric will eventually need to be solved more or less by him.

Although Professor Kikuchi didn't end in person, his identity is there.

A slight exposure of the network resources behind him is enough for Baichuan Electric to go far.

To be honest, if it weren't for the fear that Professor Kikuchi would look down on him, Bai Chuanfeng would have wanted to write a share transfer letter directly to him.

It's a pity that this kind of boss with the support of national resources doesn't like these at all.

Hard to send, but fell into the cliché, can only wait for the future.

Outside the laboratory door, Bai Chuanfeng held Yamazaki Hui again.

"Senior Yamazaki, you must visit Shirakawa Electric more often. Yasuda-san and the others miss Yamazaki-senpai very much."

This Bai Chuanfeng did not lie, after all, he had worked together happily for half a year, and he still had feelings.

Yamazaki Hui also nodded happily, "Sure, sure. Say hello to Yasuda-san and the others for me."

"No problem, goodbye Yamazaki-senpai."

Waving goodbye, Yamazaki Hui looked at the back of Bai Chuanfeng and the others leaving, and remained silent for a long time.

…

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

The specific entrustment plan has been submitted by Bai Chuanfeng through Professor Kikuchi.

According to the current preliminary budget, Shirakawa Electric will provide 20 million yen in funding each year.

For the relevant professional teams of Meiji University to conduct targeted research and development on precision servo technology and digital signal processing technology.

As for the target, it is naturally a CD.

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

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

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

Precision servo technology Shirakawa Electric will also participate, so it should not be a big problem.

The difficulty is still in the digital signal processing part, and a design solution that can be actually commercialized must be produced within three years at the latest.

This is already the longest time limit that Bai Chuanfeng can accept. The reason why he paid such a high price to make arrangements in advance is to be one step ahead of others.

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

Bai Chuanfeng knew very well in his heart, what kind of formatting competition, what is participating in the formulation of standards.

Baichuan Electric is still far behind, even if he is shy, the former people will not look at him.

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

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