Zhao Ye's design work is progressing smoothly. The reason why it is so smooth is because the entire team has been trained in the past two years.
Zhao Ye completed his part of the work early. He did not interfere with other people's work groups, and went to the Shen Ji and Microelectronics Institute.
In the conference room of Laboratory 8, Zhao Ye organized another small meeting.
"I came to see you today to ask for your help in making a gadget." After Zhao Ye finished speaking, he distributed information to everyone present.
Qin Gong from Jingyi Machinery is also here this time. Speaking of which, he lost a bet with Zhao Ye and really came to Zhao Ye to "please bear the thorns". In front of everyone, Zhao Ye can't really let him go.
Can an engineer who is almost 40 years old kowtow to himself and admit his mistake? This is not a matter of principle!
It's just that this Qin Gong still has a very upright character. He always wants to be Zhao Ye's apprentice!
How dare Zhao Ye really do this! He couldn't even take advantage of it. In the end, Director Yang had no choice but to "accept" the person. Now, Qin Gong has become the deputy director of the United Factory's Technical Department.
The reason why it is the Technical Department instead of the Technical Section is because the administrative level of the joint factory has been upgraded again. The Technical Section has also been upgraded to the Technical Department.
Everyone follows the rising tide, and Zhao Ye is certainly no exception. But he didn't care about this when he came from the east. For a time traveler, especially someone like Zhao Ye, money is not a problem at all. If you are really short of money, you can just find someone with money.
Near the mine, you can collect some gold-containing stones and extract gold from them in minutes. This is also a function that Zhao Ye discovered some time ago.
"Gong Zhao, what is this? It looks quite complicated in structure." Director Zhang from Shen Ji asked.
"Oh, this is a floppy disk reader and writer that I imagined. It can cooperate with the floppy disk to access some data." Zhao Ye explained to everyone.
"That's what I thought. Everyone has seen the tape, right? In principle, it is similar to that one, but the structure is different."
After saying that, Zhao Ye started to draw a picture on the blackboard at the back. First he drew a circle, then took the center of the circle as the center, and then drew a concentric circle, until he drew 32 circles. Then on the outermost circle
On a circle, I started to mark again, directly dividing the circle into 16 parts.
Zhao Ye drew an arc on the blank space of the blackboard again to represent one of the portions. On this enlarged diagram, he began to mark a number 64.
At this time, Zhao Ye explained to everyone again: "Look, everyone, this is the disk I want to make. Generally speaking, we divide a circular disk into 32 concentric circles. I call this "track"
", and then divide each track into 16 parts, then one part is a sector. On each sector, we are planning a 64-byte storage location, which is 512 storage units. In each sector
We plan one byte each at the beginning and end of the disk to store address information. In this way, this disk can theoretically store 15872 Chinese character information. Of course, the actual number is less than this because there are some other
Fixed information needs to take up some space. But it can definitely exceed the storage space of 13,000 Chinese characters."
Everyone listened to Zhao Ye's words and felt a little confused. Why are you telling us this? This is not consistent with the information we have.
"The information you have in hand is a device that reads and writes the disk I designed. Let's take a look at the design..." Zhao Ye explained the structural design of the floppy disk reader and writer in detail and analyzed the processing and manufacturing of this device.
difficulty.
For those who have had experience in automation design, this thing is indeed a bit difficult, but it is not very difficult. There are ready-made design solutions for servo motors and reading and writing heads, which is a difficulty, but the difficulty lies in how to make it more efficient.
Small. There are also ready-made solutions for the position sensor. This does not require laser equipment, but the floppy disk is in a fixed position. As long as the position of the magnetic head is controlled by the servo motor based on the read position information, the positioning function can be realized.
Regarding the manufacturing of floppy disks, Zhao Ye did not plan to put it here. This is not the strength of this place. He planned to hand it over to the 718 factory, using a thin plastic sheet, using the principle of a photolithography machine to perform ultraviolet rays on the chemical layer.
Irradiate and plan the tracks and sectors. Then use iron oxide as magnetic induction material and fill it into the planned storage location. In this way, just cover it with a layer of polymer material to prevent the iron oxide and air from contacting and interfering with each other.
, the core of a floppy disk is completed. Then polish the core and put it into a special shell, and the floppy disk is completed.
Although the current technology cannot provide much storage space, there is still room for improvement. For example, double-sided storage, extended sector storage units, and increasing the number of tracks.
On the classic 3.5-inch disk of later generations, people achieved a storage capacity of 1.4MB. However, the processing accuracy requirements are relatively high. Now Zhao Ye only achieves 32KB at the currently achievable accuracy. If the reader and writer can produce dual
If the magnetic head is installed, it can be doubled to 64KB.
Of course, it's a little bit small, but compared to today's cabinet-sized hard drives, this little thing is still very convenient.
The research and design of the manufacturing process of the floppy disk reader/writer or accessor has officially begun. For the current sinking machine, microelectronics, and joint factories, this is difficult, but not big. Their biggest difficulty at present is how to make this
Things are made small enough.
Because their equipment was smaller, floppy disks could achieve smaller sizes. Finally, after a long period of testing, Zhao Ye and the researchers here set the size of the floppy disk at 10 centimeters. That is to say, it is larger than the 3.5 inches of later generations.
A little bit bigger.
After the size of the floppy disk was determined, Zhao Ye began to contact the 718 Factory. Production equipment was not a problem. When Zhao Ye started research on the floppy disk project team, he had already produced the equipment for producing floppy disks in advance. This was very important for what he could do at this time.
For a joint factory that produces automated photolithography machines, it is really not too difficult. It is nothing more than simplifying the equipment, replacing the silicon wafer with a plastic sheet, and adjusting the intensity of the light and the lens.
The difficulty of this technology is the material. Fortunately, this is the simplest problem for Zhao Ye.
The size is finally determined, and the equipment is adjusted and fixed according to this size. Finally, trial production is carried out for testing.
Although 718 is a military-industrial unit, Zhao Ye and his joint factory can be considered half a military-industrial unit. Besides, the two units have cooperated many times, and this is still the improvement work of Shuguang-1, so the leaders of Factory 718
I feel this is a matter of great responsibility.
This is also true. Their report was typed and approved by their superiors on the same day. The first piece of equipment was delivered to the 718 Factory that night.
As for the production of floppy disk casings, that was not a big problem for 718. Within a few days, the plan was come up, and after confirming it with Zhao Ye, production started immediately.
As for the floppy disk reader/writer, it was made by the people at Shenji Machinery in the test workshop of the joint factory. Since it was not a mass production, there was no special production equipment and only the general machine tools here were used for processing.
A batch. Of course, many fine parts were made by Zhao Ye and his technicians.
If mass manufacturing is to be carried out in the future, then the Shen Machinery Factory will need to cooperate in the development of specialized processing equipment.
In the busy schedule, another few months have passed, and now that the new year is approaching, Zhao Ye has led everyone to assemble a new microcomputer again. This time, the improvement of Shuguang-1 is relatively large, so everyone unanimously decided
, and named the newly developed aircraft Shuguang 2.
The current Shuguang 2 is closer to Zhao Ye's ideal computer. He has two monitors to choose from. One is the dot matrix LCD display of the original Shuguang 1, which is just larger than the first generation. However,
It is also limited. This technology is really not that easy. The second option is to use a TV instead. Dawn 2 is equipped with a signal converter and a special plug interface is left on the chassis.
In addition, there are hard disk interfaces, interconnection interfaces, and floppy disk readers and writers. The gap between the computers in Zhao Ye's impression is getting smaller and smaller. This gap mainly exists in the performance of the processor. The concept of external devices is that the two are almost
We are almost "agreed".
This time, a total of six Shuguang-2 machines were built in the laboratory. This was to test the function of multi-machine interconnection. Professor Ci and the others specially found very computationally intensive data for experiments, and used one machine as the host machine.
Responsible for the decomposition and integration of computing tasks, the other five computers perform calculations separately under the command of the host. The calculated data is interconnected through the host at any time, realizing parallel computing of multi-processors and multiple machines.
At the end of the first day of testing, the good news was reported to the relevant departments. Before all the testing work was completed, the production tasks from superiors were distributed to the factory.
The joint factory has once again invested in the production of new models. This time the production is also a multi-factory collaboration, and even the Shuguang Factory, which has a heavy task, has received corresponding production tasks.
Why, because all the automated lithography equipment is there.
We can't let them do the processor, but some of the chips used in peripheral equipment are still capable. The joint factory mainly uses second-generation photolithography equipment to process the core processor, and other supporting factories produce other ancillary components.
Then they are gathered again in the assembly workshop of the joint factory for assembly.
When Zhao Ye waited until the overall test was completed, he had a hunch that he would not be able to spend this Spring Festival at home again.
This is also true. In almost the same form as last year, the first batch of completed Shuguang-2s once again requested to be sent to the Northwest as soon as possible, but this time it was not twenty units, but two hundred units.
The number of units was not just one, but nearly thirty. Without thinking too much, Zhao Ye once again boarded the truck heading to the Northwest.
