Whether experienced computer user to give at least one of the components of the system of interpretation? Every day we see the keyboard, mouse, monitor, but if we ask the question, what is the computer device enabling the reading, we are unlikely to figure it out immediately. Although this mechanism very well known.

Concept

Such issues occur for the cs problem. And they know the answers, even fourth graders. Of course, not all, but you know. But experienced PC users who all day sit at the computer can reinstall the operating system and know how to run a command line, is unlikely to immediately tell what it is. In fact, the drive – the computer device allowing reading. Further speech will go just about it.

What is this?

Perhaps not all readers know what a floppy drive. So it will be more General information about this device. We'll tell you what it is for and where is it used. It is worth to say that the drive has another name – the optical drive. This mechanism applies not only to a PC. It can be found in cars, iPods and other devices which use discs. It is a computer device that allows reading. It combines mechanics and electronics, works by laser reads information from optical discs. There are a variety of drives that are the same laser to record data.

Terminology

It So happened that the optical drive has got a large number of names. As it is called in the modern world. In addition to official names, such as the drive, it can call and just drive. We only know that the name itself comes from the English Disk Drive.computer device allowing reading and writing

If you translate primitive, we get a mechanism set in motion. As is clear from his appointment, he spins discs. Interestingly, the optical drive is not one of a kind, but the only one that is set in modern computers. And if you look at new models of laptops or netbooks, and from there he's already gone.

Appearance

What is a computer device that allows reading and writing? To say that all the drives are the same, it is impossible. It all depends on their scope. Can be as a mechanism, which is placed in the computer case. This is a monoblock option for laptops and netbooks. However, there are portable drives.

An Interface for connecting the disk drive can be SATA or USB. Previously, in older systems, drives connected via the IDE cable. This is the most common and known splice variants. But there were others, which few people remembers and knows. It connects via USB portable drive. He's not too popular but needed by those who used to use the discs at work or watching a movie. Besides, it is convenient that it can be connected to any PC.

The appearance is influenced by slight modifications. For example, most of the drive is represented by a tray that opens from a button. There is a computer device that allows reading and writing of information with an open hole. Simply insert a disk, and mechanism automatically “swallow”.

Types

Interestingly, there are now many types of actuators. They may not even be different externally, but to work with different formats. So, there is a computer device that allows reading the CD-ROM drive. Or there are variations for Blu-Ray, DVD, etc.

CD

The Drive that takes CD is the most common and the ordinary. Previously, he was particularly popular. Such a device can be of several subtypes. First, a CD-ROM which can only read information from the disk. Secondly, CD-RW, which can reproduce the data, and to record information to disk.

DVD

This is another type of disk drives, which at one time was considered a deficit. When in selling out the drives with the latest innovations in the industry, this type became particularly popular. This option also has several subspecies. There is a device for reading and recording.

Only, there is a difference. DVD-RW, besides the fact that reads and writes DVD-ROM drive, can the same be done with the CD. Later came another type-DVD-RW DL. This version did everything the same as all the previous ones, but were given the opportunity to work with a double-layered discs, which acquired a large volume. There was also the option drive DVD/CD-RW. Such a computer device that allows reading and writing at the beginning of its development was also popular. Difference was that to read the drive CD and DVD but only write CD.

Blu-Ray

Optical drive BD-RE not known to all. He was working with Blu-Ray. In this case, the disks were simply a huge amount – up to 23 GB. Despite the fact that the principle of operation did not differ, yet the difference was. Used a smaller wavelength laser. Also reduced was a blue emission spectrum. Himself the protective layer of the disk wasmore. This was due to the need for reliable protection of reader and writer.

HD DVD

Next came a combined version that worked with all types of discs. The exception was the BD-RE. This option is read and write various formats, which acquired a large amount.

Usage

At the time, a computer device that allows reading and writing was like air for every geek. PC 90-ies was not without drive. Now the situation has changed. Of course, if any system becomes more flexible. But even an operating system learned how to record on a flash drive, to not use the disk.device for reading

That the flash drive has become ‘killer" optical drive. Users prefer a small device that can be placed in your pocket or hang it as a keychain. The stick can repeatedly record information and delete. It does not need specific software and tools.

“the Last nail in the coffin” is the emergence of external hard drives. Their volume was hundreds of times more, and the use easier. First, users barely tolerate the loss of drive with laptops or computers. After you have learned to use what was at hand. Now hardly anyone comes no optical drive. Although there are still people who are happy to buy collector's edition games on disc or album in a beautiful package.
