Chapter 194 Magnetic Head
The first disk was manufactured, and at the request of the audience in the live broadcast room, South Korean won a full display of it.

Under the incandescent light, the originally silver-white aluminum alloy reflects a trace of purple-green light, which looks dazzling and confusing.

The audience in the live broadcast room was also amazed.

【so amazing. 】

[Where did these purple-green colors come from?Plating? 】

[The magnetic layer comes with it, it is the same as the CD, but the color of the CD is more than this one, this one is only purple-green, but the CD is colorful. 】

[Are these brilliance the magnetosphere? 】

[Is this high technology? 】

[To be honest, this kind of technological thing that looks so complicated and sophisticated, in my place, only costs 9 cents.]

[The sentence upstairs made me laugh instantly. 】

[9 gross?You are made of plastic, the anchor, the aluminum alloy plate alone costs more than [-] cents. 】

Seeing the barrage, Han Yuan smiled and said, "The disc can reflect colorful colors because the reflective layer inside records data."

"These data reflect different colors when light passes through the protective film under sunlight."

"But the disk in my hand is different. The source of its color is not the data layer, but the ion color of the magnetic coating."

"You can search for the colors of chromium ions and iron ions and you will know it naturally."

Explaining the sentence, Won proceeded to process the rest of the disk.

The storage size of a disk is determined by the number of disks, unit storage density, number of heads, number of tracks, cylinders, and sectors.

Regarding the amount of newly manufactured disk storage, the won does not know exactly how much it can have.

But there is nothing wrong with making a few more.

After being busy until late at night, I finally finished processing more than ten disks in my hand.

The rest is the manufacture of the most difficult magnetic head.

Putting away the disk and downloading the broadcast, Han Yuan crouched in front of the table while recording today's data, while thinking about something, thinking about it, he thought of data loss.

Traditional magnetic disks are made of plastic, aluminum alloy or glass as a substrate, and then coated with a layer of magnetic material.

If the coating is damaged, that is, the magnetic layer is damaged, or the disk is physically damaged, the data inside will be lost and cannot be retrieved.

This is a situation that human beings have no solution to today's technology. If the disk is physically damaged, the data inside will inevitably be lost.

There is simply no way to get it back.

"Is there any way to make the disk recoverable after damage?"

Thinking of this, Han Yuan involuntarily stopped writing, biting the tip of the pen and thinking about various ways.

Based on the knowledge and information he has now, in some respects, it has already broken through the current technological limit of mankind.

Although the bias is serious, he can and has the ability to think about things that break through the boundaries of science and technology.

Frowning and meditating for a while, Han Yuan suddenly started to write a line on the paper.

"Magnetic ion implantation + low temperature memory metal."

Seeing the written words, Han Yuan frowned and thought again, but his eyes became brighter and brighter.

Perhaps there is a way to combine these two approaches.

After all, atoms are indivisible, microscopically and to some extent.

Just like cutting vegetables with a knife, what is cut is only various grain boundaries between crystal grains, and does not actually cut off any atom.

It can even be said that the knife has not even touched an atom.

The same is true for the physical damage of the disk. The tearing of the metal only damages the grain boundaries, and the atoms inside are not damaged.

In fact, it is very difficult to damage or cut an atom, and the energy required is unbelievably large.

But if the magnetic ions for recording data are implanted into the memory metal, and then sorted and fixed in a unique way.

So even if the memory metal is deformed, the magnetic ions inside will still not be damaged after recovery, and the data arrangement will not be disordered, and the corresponding data will still be there.

In a way, the data is indestructible and meets the requirements.

It just means that any magnetic material has a demagnetization temperature. If it exceeds this temperature, the data will also be lost.

Therefore, in the selection of memory metals, only low-temperature memory metals can be used.

After thinking for a while, Han Yuan smiled dumbly after recovering, and started to record the rest of the information.

Even if the method of "magnetic ion implantation + low-temperature memory metal" can be used to manufacture memory, it is only theoretical.

Moreover, there are many defects inside, and the manufacturing process is extremely difficult, especially if the magnetic ions are fixed on the memory metal, it is a super difficult problem.

For these, he has no time to think and experiment for the time being, so he can only record this idea first, and maybe he will develop it later when he has time and need.

At present, the most important thing is to manufacture transistor computers.

After a night of no dreams, the next day, Han Yuan started the live broadcast as usual and walked towards the chemistry laboratory.

The virtual screen unfolded, bullet screens flew across, and countless audiences greeted him.

Han Won responded with a smile: "Good morning everyone, yesterday I have manufactured the disk for storing data."

"Then everyone knows what to do today."

Hearing this, the audience squatted and typed quickly.

[Make a magnetic head. 】

[Manufacturing magnetic heads. 】

[Hey, I know, I won’t talk, I’m just playing]

[What are you doing today? 】

【Tilapia! 】

[Copper smelting today! 】

[What do you eat in the morning?tilapia.What do you have for lunch?tilapia.What are you having for dinner?Tilapia! ! 】

[Good guy, let's let the tilapia go, sooner or later you will eat it to extinction. 】

[Good morning, worker! 】

The barrage was still weird, and I didn't know where it went within two seconds. Han Yuan didn't care, smiled, and continued:
"With magnetic storage, it is natural to need supporting reading and writing equipment."

"And this, of course, is the magnetic head."

"Compared to the manufacture of magnetic disks, the manufacture of magnetic heads is much more complicated."

"And the materials required are more precise, and the requirements for size are more stringent."

While speaking, Han Yuan walked towards the chemical laboratory.

"The quality of the magnetic head determines the storage density of the disk to a large extent. The more precise the magnetic head, the denser the data it stores."

"Structurally speaking, a magnetic head is mainly divided into three parts."

"The first part is the magnetic head sensing area for reading and writing data."

"The second part is the head support."

"The third part is a small servo motor."

"As for the structure diagram, you will know it after reading this. This is the structure diagram of the magnetic head that I designed before."

When he came to the laboratory, Han Yuan spread out the design drawing of the magnetic head that he had brought, and displayed it to the audience on the silver-white metal experiment table.

Hearing this, everyone looked over one after another.

The curious ones are not only the audience in the live broadcast room, but also the scientific research scholars from various countries who have been squatting in the live broadcast room early.

Since this period of time, South Korean Won has not broadcast any new technology or new technology. Although the things in the live broadcast are very high-end for ordinary people.

But for scientific researchers who have already mastered this knowledge and technology, it seems very boring.

Many people even turned around and went back to study the previous video of Won.

But the design and manufacture of magnetic heads is a high technology for most countries.

More than 200 countries have mastered the cutting-edge magnetic head manufacturing technology, which can be counted on one hand.

This thing cannot be produced without a complete industrial foundation, especially the magnetic area for reading and writing data, which requires cutting-edge materials.

Therefore, all countries are particularly interested in knowing how the won will be made and what materials will be used.
