What is an optical drive, what is it used to drive a disc?

An optical drive is what we usually call a CD-ROM, a device that reads information about optical discs. It is an indispensable hardware configuration for multi-** computers. Optical disc storage capacity is large, cheap, long storage time, suitable for storing a large amount of data, such as sound, image, animation, information, movies and other information.

There are three types of normal discs, CD-ROM, CD-R, and CD are read-only discs; cd-r can only be written once and cannot be rewritten again later; CD-RW is a re-erasable and writable disc. Now there are more large-capacity ***-rom, ***-r, ***+r, ***-rw, ***+rw and other discs.

The most basic indicator to measure the optical drive is the data transfer rate (data transfer rate), that is, we often say double speed, single speed (1x) optical drive refers to the read rate of optical drive per second is 150kb, in the same way, double speed (2x) refers to the reading rate of 300kb per second, and the cd-rom optical drive on the market is generally 48x, 50x or more. The high speed of data transmission is greater, but the accuracy of the data is greatly reduced, and the life of the optical drive is shortened, which increases the user's investment.

It's your optical drive. The thing that put the disc in.

It is used to enable the computer to communicate with the device.

A drive disc is a driver for some hardware such as a computer, and the driver is a small piece of the operating system that contains information about the hardware device. With this information, the computer can communicate with the device.

As a carrier or medium for storing drivers, when it appears in the form of optical storage media such as CD and ***, it can be called a driver CD.

A driver is a small piece of information that is added to the operating system and contains information about the hardware device. With this information, the computer can communicate with the device. A driver is a configuration document written by a hardware vendor based on the operating system.

pieces, it can be said that without drivers, the hardware in the computer cannot fully function. Different operating systems have different hardware drivers, and various hardware manufacturers will continue to upgrade drivers in order to ensure hardware compatibility and enhance hardware functions.

Analysis: How optical discs work.

The mirror-bright disc is made of an extremely thin aluminium or gold sound membrane with a protective layer of rolling ballast polyvinyl chloride plastic. Like floppy disks and hard disks, optical discs can store files and information in the form of binary data (a data pattern consisting of "0" and "1"). To store data on an optical disc, the data must first be converted to lumin for binary with the help of a computer, and then the data pattern must be burned with a laser onto a flat, reflective disc keypad.

The small pit carved by the laser on the platter represents "1", and the blank space represents "0".

When reading data from the disc, a directional beam of light (laser) moves rapidly across the surface of the disc. A computer or laser player that reads data from the disc looks at every point the laser passes through to determine if it reflects the laser. If it doesn't reflect the laser light (there's a small crater there), then the computer knows that it represents a "1".

If the laser light is reflected back, the computer knows that the dot is a "0". These thousands, or millions, of "L" and "0" are then restored into **, files, or programs by a computer or record player.

Many friends who use computers may know what the system driver is, and they have also installed the driver by themselves, but they don't know what the function of the system driver disc is, in fact, the system driver disc is a very easy to use driver installation tool, so let's take a look at it in detail.

Summary of Frequently Asked Questions].

What is the role of the system drive CD:

A:Used toInstall the driver

1. As the name suggests, the system drives the CD-ROM and integrates the driver into the CD.

2. When installing the machine, we only need to use the system to drive the CDOne-click driver installationFinish.

3. Because some systems may fail to operate normally due to the lack of drivers when they are installed.

4. If we want to use it, we only need to drive the system to the discInsert the optical drive, and then open it in the control panel and you're ready to install it.

5. In addition to the installation time can be used, if we appear due toThe driver cannot turn on the machineproblems, which can also be solved using it.
