章節 940: Chapter 940: First-class companies set the standard
At this time, laser disc technology had not yet reached the CD stage, and was still in its infancy as the LD laser disc.
There was no connection between laser disc technology and computers.
In terms of technical principles, there are two aspects to a laser disc: writing information and reading information.
Writing information involves using a laser to focus a beam with a diameter of about 1 micrometre on the disc medium to burn small pits into the disc. Each pit and each flat area represents a bit of information, which is used to represent the data '1' and '0'.
To read the information, a laser is used to read the information based on the difference in light reflection between the pits and the unablated areas. A modulated laser beam is projected onto the optical disc medium. In the pits, most of the incident light is returned because there is no concave area, while in the pits, the reflected light cancels out the incident light due to the depth of the pit and is not returned.
In this way, the '0' and '1' information recorded on the optical disc medium is read out based on the difference in the ability of the light beam to reflect.
Then in 1972, the Dutch company Philips introduced the Laser Vision Disc player and the Laser Vision Disc system, LD, also known as LaserVisionDisc.
LD-Laser Vision Disc records analogue signals, with FM modulation for analogue recording. The disc has a lot of space, and the storage method uses double-sided storage technology, as well as double-sided playback technology.
However, the LD-Laser Vision Disc is 30 cm in diameter, and coupled with the Laser Vision Disc player, it is very bulky. Although in 1978 Philips set the LD format standard in order to reduce costs and lower the market entry barrier, it was still unable to be widely promoted in households due to its bulky size and high price.
Then, at this time, the home cassette player appeared again, dealing a major blow to the LD laser disc player.
Knowing that it was impossible to succeed, Philips sold most of the LD laser disc format copyrights to Pioneer Corporation of Japan.
After buying the format copyrights, Pioneer Corporation launched the first LD player, the VP-1000, in July last year, and is currently developing an LD player for cars, combining its strengths in the field of car audio.
The report also said that after selling the LD format rights, Philips is researching new laser disc technology, mainly to solve the disadvantages of analogue signals and develop a new generation of optical disc storage systems.
Although technology research and development is a very secretive matter, registering patents is inevitable in order to seize the high ground in technology, so even if the detailed technical principles after registering the patent are not known, the general category of the technology can still be guessed.
Therefore, Lu Chao could determine that not only was Philips the industry leader in the world, but also companies such as the island nation's Sony Corporation, the island nation's Panasonic Electric Works, and West Germany's Siemens AG were all conducting related research.
...
After closing the report, Xia Yu began to ponder, combining the memories in his mind, pondering how he should act.
Although Xia Yu was not proficient in optical disc technology, he had heard about it before. After all, both the VCD player, which became a huge hit in later generations, and the optical disc of the Internet era were restricted by the Yellow Book and Red Book standards for optical discs.
However, these two standards were from later generations. After reading the report, Xia Yu was certain that these standards had not yet been established, and there was still a long way to go before they were established.
As the saying goes, first-class companies set standards, second-class companies make brands, and third-class companies make products!
Tiangong Electronics Co., Ltd. wants to be a giant in the field of optical discs and storage in the next few decades, and it must not miss this opportunity to become the industry standard-setter.
I remember that in the previous life, it seems that Philips and Sony jointly developed the Red Book standard and the Yellow Book standard, which allowed these two companies to stand at the top of the pyramid and suck blood in the flood of the information revolution.
Xia Yu looked at his watch and found that it was only a little after ten o'clock, and there was still more than an hour until the end of the workday.
He stood up and said to Huo Jianning, 'Jianning, come with me to the Tiangong Technology Laboratory to meet Lu Chao again. I have something to discuss with him.'
Huo Jianning knew it was about the report and readily agreed, and then accompanied Xia Yu to the laboratory.
Soon, Xia Yu was once again in the Tiangong Technology Laboratory, where he found Lu Chao intently fiddling with a precision instrument.
'Dr Lu, the chairman is here and would like to talk to you about something!'
Fok Kin-ning walked up to Lu Chao and said in a raised voice, startling Lu Chao.
The latter looked up, pushed his glasses, which were slipping down a bit because of the grease, and said to Xia Yu with a burning gaze: 'Chairman!'
Just as Fok Kin-ning had said before, Lu Chao's beard was exceptionally long, his hair was a bit messy, and there seemed to be a yellow solid in the corner of his eye.
However, despite his unkempt appearance, the eyes under his glasses were extraordinarily bright, showing a different kind of brilliance that made a deep impression on Xia Yu.
'Dr. Lu, let's stop for a moment and go to the office to sit down and chat. I've read your report and I have some ideas I'd like to discuss with you,'
Xia Yu said softly.
Hearing that it was to discuss, Lu Chao's eyes lit up even more. The other day, Chairman Xia Yu's brainstorming had given him a big shock of ideas, and now there was a chance to exchange ideas, so he was a little excited.
'Okay, Chairman, I'll turn off the equipment first.'
After saying this, he immediately turned around and deftly shut down the equipment.
Half a minute later, he arrived in the office with Xia Yu and Huo Jianning.
As soon as he sat down, he couldn't wait to ask, 'Chairman, is there something wrong with my report?'
Xia Yu placed the report on the desk and shook his head with a smile, saying, 'There's nothing wrong with the report. The content is very detailed, and it can be seen that you've done your work very carefully. What I want to talk to you about is the future of laser discs and what we can do about it!'
Lu Chao's spirits lifted, and he immediately opened the notebook he had been carrying into the office. He sat up straight, looked at Xia Yu with burning eyes, and said, 'Chairman, you go ahead!'
Xia Yu thought for a moment and found an entry point to start talking.
'The LD laser disc system uses an analogue signal and reads optical information. Although it uses a 1-micron laser beam to record data, the area on the disc is fixed. Even if it can record on both sides, the amount of information that can be stored is limited, and the amount of information that can be stored is directly proportional to the size of the disc.'
'However, the disadvantages are also obvious. It is very sensitive to interference and noise, and because it is laser beam ablation, it is prone to dirt and even signal errors caused by scratches and contamination.
'Of course, another obvious point is that it is too large, which is one of the reasons why LD laser discs have not been able to be widely promoted. Combined with a laser disc player, it seems too bulky.'
'I have some ideas about these problems.'
'The fundamental reason for these problems is actually the analogue signal, which leads to inaccurate data reading and is easily affected, resulting in reading errors.'
'So is it possible to develop a photoelectric conversion technology, such as pulse counting? Convert the analogue signal to digital processing, and then compress the converted digital signal and record it on the disc, which can directly solve the shortcomings of interference and noise sensitivity.'
'Not only that, we can encode each part of the information and determine the address. Just like a library, books of different types, such as science, humanities, military, health, etc., are sorted into different shelves. When looking for information, the required information can be found in the shortest time.'
'We can also add a scheme for error detection and correction to reduce the bit error rate.'
'In this way, we can store dozens or even hundreds of times more data on an optical disc of the same size, so the size and weight of the disc can be reduced, and the size of home-use CD players and video players will be greatly reduced, and the market will reopen.'
'The CD becomes smaller, which should be enough to develop a portable CD player.'
'...'
Lu Chao's face flushed with excitement and he said loudly, 'Chairman, your idea should be correct. This is the right way. If we really develop the product, it will make a huge contribution to the world.'
'Not only the portable music player market, but also the even larger computer market will have a huge impact.'
Xia Yu smiled faintly and said, 'Dr. Lu, if I'm not wrong, Philips and Sony are already researching related technologies and have already made some progress. If we want to catch up, do you think it will be difficult?'
Lu Chao's excitement instantly cooled, and he frowned as he thought quickly.
After a long while, he said with a relaxed brow, 'Chairman, according to the information I have gathered, the patents applied for by Philips and Sony should not yet have developed photoelectric conversion technology. It is possible that they are developing another kind of technology.'
'Thomas Edison once said, 'Genius is one percent inspiration and ninety-nine percent perspiration. But that one percent of inspiration is the most important thing.
'Since Philips and Sony have been researching for several years without coming up with a technology, it must not be a problem of research strength. They must not be in the right direction and are still experimenting and groping.'
'But my intuition tells me that your thinking is correct. Whether it is correct or not, we will know after experimenting. Our laboratory has the world's top experimental facilities. The only thing that can be considered a constraint is the elite in the field of electronics. However, I can contact my classmates and friends and perhaps find some people to come and work on the research together.'
'As long as they are willing to help me, I am confident!'
Xia Yu immediately said, 'Dr. Lu, the company has never been soft on talent. As long as you can get the people here, they will definitely be satisfied with the treatment and be able to focus on scientific research.'
Lu Chao nodded and said, "I'll go make the phone call now!'
He got up and was about to leave the office.
Xia Yu was a little between laughter and tears, and immediately said, "Dr. Lu, sit down first, don't worry, I'm not done yet.'
Lu Chao then sat back down and looked straight at Xia Yu.
Xia Yu continued, 'I suggest that when developing technology, you pay close attention to the movements of Philips and Sony. We must strive to become the leader and standard-setter in this field, which will determine the future of the company.'
'In addition, you should recruit as many people as possible. Compact disc technology represents the future, but you should not neglect tapes and Walkmans. Walkmans are cash cows for technological research and development. Do you understand?'
Lu Chao took a deep breath and nodded heavily, saying, 'Chairman, I understand everything you've said. The research and development of the Walkman has never stopped, and I will realise your vision as soon as possible.'
At this time, Fok Kin-ning also spoke up, saying, "Chairman, I will also step up supervision and speed things up while maintaining quality and quantity.'
Xia Yu nodded with satisfaction, saying, "Mmm!'
After chatting with Lu Chao for a while, Xia Yu noticed that Lu Chao was clearly distracted, probably thinking about technology. Xia Yu simply dismissed him.
After Lu Chao left, Xia Yu took a sip of tea, leaned back on the sofa, and said to Huo Jianning, 'Jianning, there is something you need to do.'
Fok Kin-ning leaned slightly forward and said softly, 'Chairman, please give your orders!'
Xia Yu flipped through the report and pointed to a location, saying to Fok Kin-ning, 'Go collect some information on the Japanese company Pioneer. Although the LD format laser disc system has drawbacks, it is not useless. It has considerable potential in the industrial and automotive fields. If it is suitable, I am prepared to acquire it.'
Fok Kin-ning took the report, looked at the words Island Pioneer Company in particular, nodded solemnly, and said, 'Okay, I'll immediately arrange for someone to gather information.'
'Hm!'
'It's almost time to go home, let's go!'
