What is the unit used to describe the speed at which an optical drive reads data?

The unit of optical drive reading data speed is double speed, and the unit of double speed is x, 1x is 1x speed, and the reading rate of 1x speed is 150Kbps; the optical drive will generally mark the maximum reading rate.

Precautions for using the optical drive:

1. Dust will damage the computer optical drive, so do not leave it in the dust If you use your computer in many places, the humid environment will affect the normal operation of the optical drive.

The DVD burner will generate a lot of heat, so do not work for a long time to avoid damage to the disc and affect subsequent use. (Recommended learning: web front-end video tutorial)

Computer usage skills:

The computer starts slowly. You can open the task manager, click Start, and change some of the things that start automatically when the computer starts. Just disable the program.

Too many advertisements when the computer starts up may be due to too much junk software. It is recommended to download software from regular application stores and do not click on unfamiliar download links.

Data expansion:

Optical drive pinyin Guāngqū; CD-ROM drive is a machine used by computers to read and write the contents of optical discs. It is also a common one in desktop computers and notebook computers. part.

With the increasingly widespread use of multimedia, optical drives have become standard configurations in many computer accessories. Optical drives can be divided into CD-ROM drives, DVD optical drives (DVD-ROM), COMBO, Blu-ray optical drives (BD-ROM) and recorders.

The optical drive is an optical disc drive, and the carrier that loads data information is called an optical disc. What reads or writes data to a disc is called an optical drive.

The characteristics of optical discs are: large capacity, low cost, good stability, long service life, and easy to carry.

Optical disc drive, referred to as optical drive, is a product that combines optical, mechanical and electronic technologies.

In terms of combining optics and electronics, the laser light source comes from a laser diode, which can produce a beam with a wavelength of about 0.54-0.68 microns. After processing, the beam is more concentrated and can be precisely controlled. The beam is first hit on the optical disc. , and then reflected back by the optical disc, and the signal is captured by the photodetector.

There are two states on the optical disc, namely pits and blanks. Their reflected signals are opposite and can be easily identified by the light detector.
