Countercurrent 1982

Chapter 1207 Golden Blank Period

While batches of technicians from Shenzhen Electronics Group visited and studied at Tianyin Electronics Factory, the video recorder factory on Bagualing has started the final debugging stage.

This time, the video recorder production line that Duan Yun imported from Japan’s Sanyo belongs to Japan’s third-generation production line, which was developed and produced by Sanyo in the early 3s. In 80, Japanese video recorder factories generally used the fifth-generation production line. Duan Yun’s production line And they are two full generations behind.

However, since the second generation of video recorders in Japan, they have already had a karaoke function. The main reason is that an analog reverb circuit is added to the video recorder, and the singing sound is dull and the layering is not strong.

To put it bluntly, the karaoke function on the second-generation video recorder is only a very small function. Even the Japanese manufacturers at that time did not expect that the later karaoke would be so popular in Japan that it became Japan's "three great inventions". One, all kinds of karaoke bars in Japan are also very popular, so when the third-generation video recorder production line came, the karaoke function was enhanced, the mixing part could be adjusted, and the microphone sound was specially enhanced.

Karaoke video recorders became popular all over the country after the 90s.

Before the appearance of the DVD player, this thing was an absolute high-end product. At that time, there were many places for renting video tapes on the street, and there were also many video halls. At that time, a deposit of 10 yuan was required for video tapes, and the rent was 2 yuan for a video tape. Two days later Send it back, and watch a movie for 3 yuan in the video hall.

However, the movements and magnetic heads of domestic video recorders at that time were all Japanese, mainly Panasonic and Toshiba, and the circuit boards were all Philips.

As for the source of components, they are from Japan to Taiwan Province, and then to the southeast coast, and then they are transformed, assembled and sold to the mainland.

The same is true of the later DVD players of this routine. Many DVD players we have seen started in this way. The domestic VCD chips are actually products from Sony, Philips, and Panasonic. As for the circuit boards, they are assembled by the Chinese themselves.

Although Duan Yun has introduced a full set of Sanyo video recorder production lines, some key components still need to be developed by himself.

Originally, this was a pit dug by Sanyo Company for Duan Yun. They sold this production line to Duan Yun at a low price, but the most critical production equipment for the magnetic drum part of the video recorder was missing. Originally, they wanted to introduce this production line after Duan Yun , it is necessary to buy a video recorder drum at a high price from Sanyo.

In fact, until the mid-90s, VCR drums were still unable to be produced locally. The most important reason was that the processing precision of VCR drums was very high. Domestic manufacturers were unable to mass-produce such high-precision drums. .

However, what Japan's Sanyo Corporation did not expect was that Duanyun's Tianyin Electronics Factory already had the ability to design and produce video recorder drums.

Duan Yun has always attached great importance to product technology research and development during the past three years in the production of electrical appliances. Over the past few years, the company has accumulated a certain amount of technology. The tape recorder magnetic head production technology imported from Japan has been completely digested, and all of them have been domestically produced. It has also upgraded and improved the magnetic head. It can be said that the magnetic head technology of Tianyin Electronics Factory has gradually caught up with the level of international mainstream products, and there is only a gap of less than two years with the top production technology of magnetic heads.

The magnetic drum of a video recorder can be regarded as an enhanced version of the magnetic head. There is a miniature stepping motor built in the magnetic drum, and 3~5 magnetic heads are embedded in the bottom. The working surface of the magnetic drum is the key part to ensure the tape runs smoothly without deformation, so The precision requirements of some parts are very high, the gap is only one micron, and the surface finish must reach 0.5 micron. This processing accuracy cannot be achieved by most domestic machinery factories, let alone mass production.

Duan Yun’s machining factory imported Taiwan’s five-axis CNC machine tools, and in order to produce tape recorder heads, Duan Yun specially designed a set of fixtures for him at that time, using three passes and one root cleaning, the accuracy is basically close to The level of the Japanese original magnetic head.

The only drawback is that the magnetic head processing method adopted by Duan Yun is slightly less efficient. The two CNC machine tools can only process more than 200 sets of VCR magnetic drums per day.

However, as the R&D team improves the production process of the video recorder head, the processing efficiency will become higher and the cost will be reduced. Moreover, in the current situation where the domestic market is unknown, the output of 200 sets of video recorders per day is considered very high.

However, Duan Yun has full confidence in the domestic video recorder market.

Video recorders were one of the 80 commodities restricted by the state in the 24s. The legal domestic sales channels of foreign video recorder manufacturers were Friendship and Overseas Chinese Store System with duty-free import rights. Imported video recorders purchased by ordinary consumers at various social and commercial outlets were not The smuggled parallel imports are private goods seized by the customs, purchased by the commercial department and issued a shipping permit number for sale in various provinces and cities in the inland.

In fact, as early as 1983, someone proposed to develop the domestic video recorder industry. However, after long-term research and discussion, at the beginning of this year, the Ministry of Electronics Industry came to the conclusion that "video recorders are advanced consumer goods in China and should not be developed prematurely." The result of this is that after 1989, under the powerful advertising campaign, Japanese video recorders opened the door to China in one fell swoop, stimulating the hunger and thirst of the Chinese people. Although there are very strict restrictions on the introduction of video recorders in China, the Under the situation that consumers' desire to buy video recorders is getting higher and higher, the Ministry of Mechanical and Electrical Engineering has successively confirmed 11 designated production plants of video recorders, but at that time the golden opportunity to develop the domestic video recorder industry has passed.

In 1992, the number of TV sets in the country reached 4000 to 800 million, while the number of video recorders reached 1 million. According to the general laws of foreign countries, the social ownership of video recorders and the social ownership of color TVs are 5. :[-], the domestic situation basically conforms to this rule.

Japanese video recorders did not officially enter China until the end of 1989. By 1991, there were 800 million video recorders in the country. This is definitely a golden blank stage in the market. If it is put into production, as long as the quality is reliable and the price is lower than that of smuggled parallel imports, then it can seize this golden blank period in the domestic market nearly two years earlier than Japanese manufacturers.

Fast forward to mid-September, and after a walkman production line has been transferred, Duan Yun arranges the vacated workers directly to the video recorder factory for learning and training, and strives to put the entire video recorder production line into operation before the end of the year...
