The cost difference between glass and plastic is not significant, but glass has a fatal flaw: it will shatter if dropped. Plastic, at least, won't shatter and can preserve some data, but a broken glass base results in a much greater loss.
An incompetent IBM technician said, "Then let's use a tempered glass base!"
Xing Baohua seriously suspected that these technicians were just there to freeload!
But thinking about it, it makes sense; they did indeed invent glass hard drives.
The technology is quite impressive; it seems that Great Wall introduced this technology from IBM, but the results were simply appalling.
Let's start by using plexiglass as the base, as suggested by the IBM experts.
The cost of the experiment kept rising, and if Xing Baohua didn't have money to burn, he really wouldn't have been able to withstand this kind of torment!
During a conversation with IBM technicians, Xing Baohua asked, "Since glass can be coated with metal, can it be coated with magnetism? Given the stability of glass during high-speed rotation and its resistance to high temperatures, could it be used for long-term data storage?"
These words left the IBM technicians deep in thought.
The technician nodded and said, "Theoretically, it's possible, but we'll have to verify it when we get back."
At the same time, he explained the hard drive structure to Xing Baohua, as well as the technology of the read head on the disk. Most hard drives nowadays use aluminum as the base material. When reading data at high speed, the data is composed of binary data such as 1 and 0. However, there are uneven textures on the disk surface, which are almost invisible to the naked eye and can only be seen with a microscope.
Concave represents 1, and convex represents 0. Reading and writing involves repeatedly brushing these concave and convex binary data with a spiked tool.
Erasing and writing simply smooth out these uneven textures and then uses the characteristics of binary code to write data.
This is the most basic characteristic of a hard drive.
What if the optical discs in the hard drive were replaced with glass? Then how would the read/write heads be upgraded? That's another technology; read/write heads can't be like laser heads.
In any case, Xing Baohua has already led IBM's technical staff into another trap.
This is a road of no return!
Glass hard drives are indeed very good, with large capacity, but they have many problems. In any case, they ruined a lot of hard drive manufacturers, and eventually even IBM itself stopped using them.
Surprisingly, the plexiglass substrate produced in the lab two weeks later was quite stable in the experiment.
The aluminum coating on the base plate provides excellent stability, but some wear and tear occurs during laser burning.
The final result is much better than the previous one using plastic; it can be written to three or four times.
Okay, let me state in the instruction manual that, apart from the original manufacturer's discs, discs made of other materials may result in data loss due to quality issues, which is unrelated to the device.
If you're going to rip someone off, you have to be upfront about it and clearly explain what materials and technologies the original manufacturer used.
After resolving the technical issues, the design was finalized and mass production began.
