The rise of nanometers

"Mr. Huang, I'm sorry for being late."

Huang Xiuyuan smiled: "Don't look outside. I told you not to disturb the experiment. Sit down and have a sip of tea."

The tired Miao Guozhong picked up the black tea on the side and drank it in one gulp, then took a long breath.

Lin Baijie asked curiously: "Guozhong, what are the difficulties with glass discs now?"

What the Ministry of Industry is most concerned about is the transformation of technology into commercialization. If industrial production is very difficult, it means that commercialization has little value.

Miao Guozhong explained: "The production technology of glass optical discs now has the conditions for large-scale production. What needs to be improved is the recorder and reader. Of course, for an enterprise's database, the recorder and reader are not the same. No impact.”

Lu Xuedong and Huang Xiuyuan, who understand this technology, understand what this means.

Ordinary consumers and businesses, official institutions, museums, etc. actually have different needs.

For ordinary consumers, a reader the size of a cigarette box may be acceptable, but a recorder costing RMB 50,000 to RMB 60,000 is certainly something that few people will buy.

But these shortcomings are not considered shortcomings for enterprises. After all, hundreds of thousands of tape drives have been purchased, and fifty or sixty thousand recorders are just a drizzle.

"If the area of ​​the glass disc is expanded to about one square decimeter, can it be done?" Lin Baijie continued to ask.

Miao Guozhong reminded: "The problem is not big. You can use a layout similar to optical disc sectors. However, if the area expands and the reader does not improve accordingly, the reading speed will decrease."

Huang Xiuyuan is quite satisfied with this performance: "For cold backup, the reading speed is suitable. There is no need to pursue the ultimate. Cost-effectiveness is the most important."

After all, the integrated area is 1 square decimeter, which is about the same size as an ordinary optical disc, but it can store 9200G data.

In addition, the retention time of glass optical discs is very long, the data loss rate within a hundred years will not exceed one part per million, and they are very easy to maintain.

It is a coveted storage medium for Internet companies, financial companies, official institutions, libraries, and disaster recovery centers that have a huge demand for data storage.

Lin Baijie nodded: "Indeed, just like the two tape databases of time information, the reading speed is really impressive."

"Actually, the reading speed is not impossible to improve." Lu Xuedong said suddenly.

Huang Xiuyuan asked curiously: "Oh? Xuedong, how do you plan to solve it?"

"very simple……"

Lu Xuedong explained his solution, which was to burn a multi-layer directory on the glass disc.

If it is a one square decimeter glass disc, the glass disc is internally divided into 100 storage areas. One of the storage areas is a directory area, and this directory records the information directory of the other 99 storage areas.

When specific data is needed, it can be searched in the directory area first, and then the reader locks the corresponding storage area to achieve the effect of quickly reading the target data.

Although it takes up one percent of the storage area, for a glass disc with a huge storage capacity, it is still more cost-effective to sacrifice this storage capacity in exchange for faster reading speed.

You can accurately find the required information within a few seconds. In addition, if you are building a large database, you can also set up a general directory disk to specifically determine which glass disc stores what information.

"This method is good." Huang Xiuyuan affirmed this solution.

Lin Baijie thought of another question: "Guozhong, will the glass disc be incompatible with the existing electronic hardware system?"

"You don't have to worry. Both readers and recorders can be connected to electronic hardware in multiple formats. After all, everyone's foundation is derived from binary." Miao Guozhong explained.

After listening to the explanation, Lin Baijie made a preliminary commercialization assessment: "It seems that the technology of glass optical discs is relatively mature. I will let the technology transformation team evaluate it in detail and come up with a complete commercialization plan."

"Okay, it's a certainty that glass discs will replace tape reels." Huang Xiuyuan also nodded in agreement.

In the current storage media market, a 1T mobile hard drive costs 340 yuan, a 1T solid-state drive costs 1,000 yuan, and a 1T magnetic tape only costs 34 yuan.

According to the internal cost assessment of the Scientific Research Department, the cost of a 1T glass optical disc is about 5 to 7 yuan.

Regardless of cost, storage capacity, data stability, service life, reading speed, and supporting costs, glass optical discs beat tapes instantly.

If it weren't for the inability to modify the recorded content, even the hard drive of a desktop computer would be massacred by glass discs.

Huang Xiuyuan made a decision: "Produce a batch for Time Information to trial, and then prepare to launch it on the market."

"Mr. Huang, is the glass disc business classified as Dragon Totem, or is it?" Lin Baijie asked hurriedly.

"Paddle to the dragon totem!"

Miao Guozhong's expression suddenly became excited. Entering commercialization also means that his team has the patent dividend of glass optical discs and is expected to obtain shares in the company.

His tone was slightly trembling, but more of an irrepressible excitement: "Mr. Huang, please give the glass disc a name!"

Huang Xiuyuan pondered for a moment and said a name: "Then let's call it Lilong! A giant dragon made of glass."

"That's a good name." Lin Baijie smiled.

Finally, Huang Xiuyuan gave a few words of encouragement to Miao Guozhong and others, and told them to continue in-depth research and development and develop in the direction of modification and larger capacity.

If glass discs can be modified and burned, then there will definitely be a place for glass discs in data storage on desktop computers.

After inspecting the glass optical disk laboratory, Lu Xuedong took Huang Xiuyuan and Lin Baijie to other laboratories to understand the progress of various current scientific research projects.

After a whole day of inspection, coupled with previous inspections at various research institutes in Shandong Province, Huang Xiuyuan had a rough understanding of the scientific research progress of Suiren Company.

That night, after having dinner with Lin Baijie and others, he returned to the office and prepared to think about recent scientific research work.

Zhang Lei knocked on the door.

"Come in."

"Mr. Huang, the invitation email for the United Nations Climate Negotiations Conference." Zhang Lei handed over a printed invitation email.

Huang Xiuyuan did not open it, but put it aside: "You are inviting me to Bonn, Germany?"

"Yes, the meeting is from August 10th to August 14th."

Huang Xiuyuan ordered: "Just say that my schedule cannot be accommodated, let Li Guizhao continue to lead the team to participate, give Li Guizhao a word, talk less and watch more, communicate more with the official team, don't make promises or express opinions at will."

"Understood, I will tell Vice President Li."

Suddenly Huang Xiuyuan reminded: "When they arrive at the local area, ask them not to go out alone or meet guests. People from the security department will record and videotape them so that they don't get jumped by the immortals."

"Understood." Zhang Lei nodded hurriedly.

Soon, Huang Xiuyuan was alone again in the office, thinking alone and calmly.

The wind in July is noisy and hot.

The night outside the window and wall is so dark and obscure.

There is a bright moon and stars in the night sky.

There are also scraps of copper and iron in the stagnant pond, and the scavenging insects and rats.

As the night deepened, there was a sudden burst of lightning and thunder, followed by strong winds and rain, and raindrops slapped on the glass windows. The early morning night rain was long and distant. I don’t know when the light of dawn would break through this long darkness.

Happy New Year’s Eve and all the best!
