When I returned to Chiyoda Ward from Chuo Ward, it was getting late.

Unsurprisingly, the lights upstairs were already on, and I changed my shoes and took off my coat.

The nanny, whose name is also Jundai, takes his briefcase and tells him that dinner is ready.

Shirakawa Kaede nodded to indicate that he already knew, but he had no interest in dining for the time being.

The appearance of the nanny reminded him of the girl he met in the tearoom today, and what happened in the courtyard.

Went upstairs and pushed open the bedroom door. Yuko Tanaka was kneeling on the wooden floor, arranging his clothes.

"Eh, Shirakawa-kun." She lowered her clothes and got up to greet him.

In fact, these jobs can be handed over to the nanny, but she never pretends to be someone else's hands.

"Yuko, pinch it for me." Kaede Shirakawa untied the watch in his hand and threw it on the bed.

Yuko Tanaka was stunned for a moment, and then nodded happily. "Shirakawa-kun, please lie down."

She straightened up the large, somewhat exaggerated double bed, and sat down on it again. And patted his legs, signaling that everything was in place.

Shirakawa Kaede smiled, then lay down on her back and rested her head between her soft legs.

His eyes had just closed, and his gentle hands were slowly kneading the sides of his temples.

A soothing warmth slowly dissipated, and Shirakawa Kaede subconsciously breathed a sigh of relief.

"Yuko's legs are as comfortable as ever."

"Eh" Yuko Tanaka didn't know if he was really praising his legs for being comfortable, or if it was another level of comfort, so his face couldn't help but blush.

"I never get tired of playing."

"Hey, it's rude."

Hearing her strange voice, Shirakawa Kaede couldn't help laughing.

"Facts," said this, Shirakawa Kaede's hands began to be dishonest, and he carefully felt her softness in the sojourn.

moved slightly, but didn't get out of his clutches, and Yuko Tanaka let him go.

She always felt that there was something abnormal with Shirakawa Kaede today, was she too busy at work, or had she been under too much pressure recently?

But no matter which one it is, what Yuko Tanaka can do is to give him a warm harbor.

As a neon woman, she also has some traditional concepts inside, and serving Shirakawa Kaede at this moment is what she wants to do the most.

Shirakawa Kaede has indeed suffered a great impact on his cognition today, and the revelation of the school valve and the chaebol finally made him recognize the tip of the iceberg of this society.

However, this opened corner also gave him a lot of pressure.

Where should Shirakawa Electric go in the future, how should I deal with them, and how should everything in Shirakawa survive in the future?

All of this is really annoying.

Shirakawa Kaede rolled over and buried her head in her soft room.

"Yuko, let me study your legs carefully. It seems that the resilience has risen sharply recently, is it quietly going to the gym. ”

The cheeky Kaede Shirakawa decides to leave the annoying questions behind first and enjoy the beauty in front of her.

"Shirakawa-kun~" Yuko Tanaka's coquettish voice was a little helpless.

This guy has been getting more and more domineering lately, and the bed between the sheets has made her more and more difficult to parry.

Hmm~, but now it seems that the effect of maintaining the figure is still very immediate, and I will continue to work hard in the future.

Shirakawa Electric Engineering Center, Ota Ward.

Shirakawa Kaede is taking Heitaro Nakajima and them around a strange-looking machine.

"Is the job stable? How effective is it? He frowned as he looked at the black box in front of him.

That's right, it's a real cube black box, stupid and crude.

It was also the first prototype of a CD player from Shirakawa Electric, and today it finally showed its true face.

"At present, the use is not bad, although there is a situation of skipping saucers, but it is barely acceptable.

The 16-bit sampling rate brings unparalleled listening enjoyment.

The bitrate of 1411Kb restores the most essential effect of sound to the greatest extent.

There is also a laser head that reads the disk information without contact, which is really incredible. ”

The more Yasuda spoke, the more excited he became, and the performance of the CD prototype was completely beyond his imagination.

He was amazed by the absolute silence of the CD player alone, because there was no friction between the laser and the disc surface, so the signal-to-noise ratio increased.

This makes the disc work, there is no rustle when the tape player and vinyl machine rotate, and the sound is clear and transparent.

This is definitely the first time for Yasuda, who has come into contact with CD players for the first time.

However, Shirakawa Kaede listened to the sound of music coming from the CD player, but occasionally frowned.

The bitrate of 1411Kb has indeed raised the sense of hearing by more than one notch, and the bitrate of MP3 in later generations is only 320Kb.

So it is conceivable that CD is definitely the existence of MP3 in terms of sound quality.

Later, in the HIFI enthusiast circle, the 1411Kb bit rate is also the real dividing line between lossy and lossless.

As for some platforms advocating that as long as the 320Kb bitrate exceeds MP3, it is a declaration of lossless sound quality, which is completely a manifestation of bad money driving good money.

Today's CD camera laser head reads the information and transmits it directly to the DAC decoding chip.

Because there is no middleman to make the difference, the sound quality is completely restored.

Yasuda: It's the first time they've seen this kind of CD player, but Shirakawa Kaede isn't.

It was only a short moment before he felt a slight skipping disc in the CD player in front of him.

You may not feel it if you don't look closely, but as a trendy product of the next generation, you must fire the first shot.

In terms of sound and experience, there must be no flaws that can be heard by human ears.

"The vibration caused by the rotation of the disc occasionally affects the reading information of the bald head, so let's try to improve it as much as possible.

In addition, "Shirakawa Kaede patted the prototype in front of him, but suddenly there was a "click", and the prototype under his command directly struck.

This made Shirakawa Kaede's unspoken words stuck in his throat. After two seconds, the CD player slowly resumed working again.

Yasuda watched this scene in embarrassment, and the other researchers in the studio were also flushed.

Shirakawa Kaede shook his head, "There's still a lot of room for improvement, keep working hard."

Nakajima-san, tell me about how Sony is progressing there and how they are solving this problem? ”

If you want to say that the real expert of CD, of course, it is Heitaro Nakajima in front of him.

He is one of the real participants and developers of CD technology, and the team of Shirakawa Electric may not be able to match him alone.

Heitaro Nakajima heard Shirakawa Kaede's greeting and stepped forward without hesitation.

Now that he is out of Sony and has no identity restrictions, he dares to speak his mind.

Thinking about the previous few months, I was sitting and drinking with Shirakawa Kaede, and the latter laughed and asked him to point out the research and development of Shirakawa Electric's CD player.

At that time, he was still struggling with the issue of identity, but he didn't expect to join the other party's camp in a blink of an eye.

What was a joking agreement turned out to be a prophecy.

Fate is wonderful.

Retracting his thoughts, Heitaro Nakajima touched the prototype in front of him and instantly found the problem.

"Too light," he tapped on the prototype's casing, making a crunch.

"Huh?" Yasuda seemed to understand what the other party meant.

"The fastest and most effective way to solve the seismic problem is to increase the weight of the fuselage."

Heitaro Nakajima opened the door of the CD player and knocked on the case again.

The disc inside the CD player, which was visible to the naked eye, was shaking slightly, and this time everyone understood why.

Because of the plastic casing, the weight is lighter. Occasional collisions can cause the disc to vibrate.

When the CD player is working, the internal disc is spinning at high speed. Any vibration will be amplified by the laser head and cause the information to fail to be read.

"Sony's solution, in addition to optimizing the mechanism design, is to switch to an all-metal body.

As the weight increases, the vibration of the CD player will be greatly weakened due to the existence of inertia, thereby reducing the occurrence of disc hopping. ”

There are also some non-compete restrictions between Heitaro Nakajima and Sony, but they have been settled by Kaede Shirakawa.

He only participated in the development of CD technology, and he was not responsible for the development of the CD player, and he was already the president of Aihua at that time.

Because of this, coupled with the appearance of Shirakawa Kaede, Sony did not bite at this point.

Moreover, the CD camp also needs more players to join, and vinyl and cassette tapes are the enemies of CDs.

Although Heitaro Nakajima did not participate in the development of Sony's CD player, this information could not be hidden from him.

Moreover, CD technology is closely related to the CD machine, and no one knows how it works better than him.

"However, there is also an obvious drawback to this, that is, the cost will skyrocket."

"Huh?" As soon as he heard this, Shirakawa Kaede instantly grasped the point, "Based on Nakajima-san's estimate, what is the approximate cost of Sony?" ”

"An all-metal body weighing dozens of pounds, plus various material devices. A conservative estimate is that the cost will exceed 100,000 yen, or even more. ”

"100,000 yen?" Shirakawa Kaede was surprised by Heitaro Nakajima's answer, "Then if you want to make a profit, the price is at least 150,000 yen or more." ”

"That's right," Heitaro Nakajima nodded, "I've heard some rumors that Sony's first CD player is likely to cost close to 170,000 yen. ”

"It's too expensive!" Shirakawa Kaede shook his head, "As a consumer electronic product, this price is too expensive. ”

Whether consumer electronics products can be widely accepted by the public, price is the most direct impact.

The reason why Shirakawa Electric's Walkman has become one of the mainstream is because it is cheap enough and most people can afford it.

However, the price of 150,000 yen basically dissuaded a large number of people.

Perhaps only those audiophiles who pursue sound quality will be willing to consume.

But if the CD player is only positioned as a niche high-end product, it is not in line with Shirakawa Kaede's original intention, nor is it in line with Shirakawa Electric's strategy.

Shirakawa Kaede looked at the desktop CD player in front of him, and suddenly raised his eyebrows, and had an idea in his heart.

"We're not making desktop CD players anymore!"

"Huh?!" Both Heitaro Nakajima and Yasuda were surprised.

Don't make a CD player anymore? What do you mean, you can't just give up all your current work, right?

"Put the desktop CD player first, let's make a portable CD player first!"

Shirakawa Kaede suddenly remembered that he could carry a CD player with him in the future like a Walkman.

Lightweight, flexible, cheap and compact, that's what consumer electronics should look like.

Only by satisfying these two characteristics will there be a basis for being accepted by the majority of consumers.

"Portable CD player?!" Heitaro Nakajima and Yasuda looked at each other.

They had never thought of a portable CD player, and they didn't have the concept in their minds at all.

"That's right" Shirakawa Kaede nodded, reaffirming their guess.

Even he had already gotten his hands dirty and was ready to tell them what a portable CD player should look like.
