Chapter 85 Data CD

The core of X's core and Microsoft computer is almost the same as memory. Microsoft's memory is several times that, so through the hardware opened by Jatali, they want analog system, it is entirely possible.

After the investigation, Catherine is now, the other party not only has opened this hardware, but they also made a game for X. Before that, it seems to be influenced by Catherine's GME-TV, so I opened an arcade-than Catherine early.

This arcade name is "space hegemony", but because the game is too complicated, it will fail.

After that, Catherine opened X. The company's roll is coming, starting to open software. This time I learned a lesson. Now, I have become a gambler for a word of mouth.

Catherine's X is the only home computer media. There is no other company that is not aware of this benefit - but Catherine thinks, they will soon be involved in this regard, because X's sales are too good.

Military users bring to the prosperity of the game makers, not to mention, and X is still soaring.

A emerging market is opened, which means that people who want a piece of a piece of people are more and more.

However, Catherine is not worried, because she took a low price strategy at the beginning, but more importantly, she has opened a heavyweight game such as "grade Mario".

For this Yadali company, Catherine is ready to observe their company's actions. If it is not, Catherine will choose to purchase directly. In this case, there is no problem. However, this is also a wake up, at least next-generation computer and game console, she is absolutely not taking the same architecture.

Fortunately, it will now buy a microsoft computer to play the game's ordinary users, while X and Microsoft computers buy less, so the damage caused by this matter is not too big.

For example, Catherine is the most headache, or the code of the optical drive.

The 6-digit CPU is being stepped up, and it is expected that up to 968 will make breakthroughs, and it may only take only 969 years, or year. However, the research of the CD-ROM drive is a bit trouble. After all, the people available in this industry will be more than the semiconductor.

"Normal code rate ..."

Catherine suddenly flashed. What did her thought.

If ... use comparison read methods?

Catherine's ideas went through the brain.

Yes, a separate piece of data, the error rate is indeed too high, but if you can use the exact same data, comparison and input?

In this way, even if the data has an error, as long as the additional two-end data does not have an error, it is possible, and in fact, the possibility of two data errors is extremely small.

For example, the data original data recorded by this place is "", and on the three sectors recorded, "O", "O", "O", respectively, so that such an error, finally read it. Data, it is still "" ".

In addition, the proofreading code and error correction code are also able to sway

In this way, the error probability of the data can be minimized.

Catherine immediately verified this idea.

In this case, three laser heads need to be needed. These three laser heads will be installed in the form of a positive triangle in the optical drive because it is in a symmetrical position, so it can be used to read data synchronously.

In the computer reading process, scanned to three binary belongings, for example, "", "" "" O "," "" "" "" "" "", "O", so that you can Available in the storage stability of data.

This data disc can store the data of the MB, which is already enough for now.

Not only for the glory game machine, such data can also be used to record software and various programs.

Although the optical drive has some cost, but overall, it is not too high, so this plan is completely feasible, and there is no problem on the computer.

In this way, the full-functionible E software can be manufactured.

The storage capacity of MB can leave a lot of room for the software, which is very convenient for operation.

Catherine ran to the light storage research department that has been integrated alone.

"We are now doing data disc"

The first sentence of Catherine scared the employees.

"Hey ... Miss Edson ..." The supervisor came over.

"You ... you ... what is your name?" Catherine suddenly remembered the technician who often introduced D schedule, she actually didn't remember the name of the other party.

"My name is Tamor Ryder."

"Tiger. Red? This last name is really rare."

"This is my own change, I want a different name, the tiger can show my domineering, and red can always let people think about fear."

Catherine shrugged.

"That ... Mr. Ruide, our next work is to open the data disc."

Catherine's order.

Ruid is some unexpected: "However, Miss Edson, we have been on the data disc ..."

"No, I am talking about the production of finished products."

Catherine took the head and she suddenly thought of her plan yet.

As a result, Catherine explained his plan again.

Now the process problem, on the one hand, the laser head misread - this is usually the most prone to the optical drive.

But now the problem is not over there, but the disc itself.

Because the disc is originally a grouped product, it is likely to have an error while can't appear, this error is almost can't see, but once it is made, it will appear many times. It's a headache problem.

In fact, in the history of Catherine, I have launched the high capacity CD of MB, but unfortunately, now Catherine, only such a product.

"indeed so."

Ruide also thought about it.

If it is a game disc, especially in the 6-digit CPU, the capacity is too large, and what is not available, unless D technology is implemented. Moreover, even if the D technology is realized, the capacity is sometimes second, such as Nintendo of the Mars compression method. You can completely compress the two discs, the capacity of MB is completely compressed on a 64MB card belt ...

"Well, our next research direction is this."

Technician consciously moved to the front. They know that this is Catherine to prepare for their own ideas.

Catherine's ideas, each time will have a big impact on technicians, and bring more inspiration - Catherine's ideas, most of them come from later worlds, it is the future trend.

Catherine said after this idea, let the research department began to study, this kind, the technical difficulty is also a lot, the data optical drive wants to study, is not too difficult.

Back to the office, Catherine stretched the chair, then unspecified the kong on the table, and then began to think about it.

CD, use digital information records, is there?

The laser disc, that is, D, the signal recorded is an analog signal. The processing mechanism of analog signal refers to analog TV image signal and analog sound signal to pass through FM frequency modulation, linear overlapping, and then enlargement. The signal subsequent signal is shorter than the long-length pits of o.5 microns.

The size of the laser disc in history is large enough, almost equivalent to o. Rice, it is therefore, it is only silent.

And Catherine's D, converting all image messages into brightness information, so that the space required to record data can be greatly reduced, but it is because of this, the sub-plate is to do things.

In the data disc, the method of data records is to turn a continuous pit into a "point", and the requirements of the process suddenly rose a grade, each point track is at least ~ microscope; orbits It is ~ micrometers, or even above, can record the data on the disc.

In fact, Catherine has always been a person who advocates simulation, what is digital, just for the sake of interest.

The only problem with simulation is to transfer and replicate, if the source is directly played, the absolute simulation of N times of the superior digital mode O is met.

However, the simulation method achieves lossless replication, but it is too difficult, the application on the CD is just a special case.

For example, the film after copying, the clarity is already a grade, and after multiple replication, the picture will become very bad. The figures of digital methods are just some data, and can be replicated anytime, anywhere, which is very convenient.

And there is a problem with the simulation method, which is why many old movies feel a little yellow, and since the movie after the era, it is difficult to judge the film from the visual effect of a single picture.

Of course, this is not absolute.

If your fluorescent disc can be branched, you can complete the lossless copy, use it in the cinema screening, there is no problem, the cost is more cheaper than the film.

It's a pity, Catherine is a recent laboratory, so the funds have some strikes, but also to go to the east, so the plan of the three-in-computer program, and the plan of the fluorescent disc, it is only a plan for the time being.

However, Catherine has decided, just wait until after turning the IBM and Motorola, you will do our own.

However, as far as is currently, the trend of the times is digital, then the number is refined. Waiting for human beings to a certain extent, when pursuing greater visual enjoyment and better experience, they may start pursuing simulation display.

In Catherine, the difference between people and animals is probably that animals are using "simulated" way to cognition this world, and people are in the "digitized" way to look at this space.

For example, people will think that gravity addresses are 9.8. And the animal does not have this feeling, they just feel this, yeah, just like this, good.

But things can be strange, because if it is minimized to the molecular interface, the simulation of nature will become digital.

This world is very wonderful, no one knows what is the main source of our world.

Fluorescent disc. "

Catherine wrote a vocabulary on the notebook, then spent a five-pointer.

This type of disc is the future trend.

Try thinking, you can enjoy the visual enjoyment of the theater at home, is there more wonderful things than this?

Moreover, you can take some fun things, such as what is the Ersa taking a shower ...

Catherine's thinking farther, but this time, the office is ringing ...
