What is the difference between an optical drive and a recorder?

The computer partners should know the optical drive, the optical drive, the optical drive, the computer used to read and write the contents of the optical disc, is also a common part in desktop and notebook portable computers. With the increasing use of multimedia, optical drives have become standard in many computer accessories. The optical drive can be divided into a CD-ROM drive, a DVD drive (DVD-ROM), a COMBO, a Blu-ray drive (BD-ROM), and a recorder. So, do you know what is the difference between an optical drive and a recorder?

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

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

       The optical drive is referred to as an optical drive, which is a combination of optical, mechanical and electronic technologies. In terms of optical and electronic combination, the laser source comes from a laser diode, which can generate a beam with a wavelength of about 0.54-0.68 microns. After processing, the beam is more concentrated and precisely controlled. The beam is first hit on the disc and then reflected back from the disc. , the signal is captured by a photodetector.

       The recorder, CD-R, is the abbreviation of English CD Recordable. The capacity of the CD-R disc used is generally 650-730 MB. It records the data in the same way as a general CD disc. It also uses the reflection of the laser beam to read the data, so the CD-R disc can be read on the CD-ROM. The difference is that the CD-R disc can only be written once. . There are two types of recorders: one is CD burning and the other is DVD burning. Use the recorder to burn audio and video discs, data discs, boot disks, and more. Easy to store data and carry. The CD capacity is 650-730MB; the DVD capacity is 4.7-9.7G.

       The capacity of the CD-R (English Compact Disc Recordable) disc used is generally 700 MB. The information on the above is the same as that of a general CD disc. It also uses the reflection of the laser beam to read the data, so the CD-R disc can be read on the CD-ROM, the difference is the CD-R disc. It can be written once, and the CD-RW disc can be erased repeatedly, so it can be used repeatedly. In theory, a good CD-RW disc can be erased about 1000 times, which is very suitable for the backup of small files, and its price is not very expensive, about 5 yuan. So for environmental protection and affordable, or buy a CD-RW disc for backup, use CD-R disc to burn something that is often needed and will not change, such as the system disk.

       The difference between the optical drive and the recorder: the optical drive only has the read function. The recorder can be read and burned. On the model number, the optical drive is a CD-ROM (or CD-R\\DVD-R) and the recorder is a CD-RW\\DVD-RW. Note the last two letters, "R" is the first letter of the English "read", and "W" is the first letter of the English "write". To burn a disc, you must purchase and install a recorder. At present, the recorder is quite cheap. It is recommended to buy a DVD-RW, which can be engraved on a DVD disc or compatible with a CD. After installation, you also need to install a burning software to perform the burning operation normally.

       The above is the difference between the CD drive and the recorder. Do you know about it?

Home Study Desk

The height of the elevating study table can be adjusted by itself. For example, when a child is doing homework, he can adjust it to the most comfortable and suitable height according to the height of the child, so that when the child is doing homework, he can avoid hunched over the chest or tilted his head too much. The sitting posture of the child and the use of a desk with a suitable height will have many benefits for the child's sitting posture and physical development after a long time.
Enterprises specializing in the production of intelligent office supplies, using intelligent production, with multi-functionality, electric control of the lifting table control, more intelligent, more accurate, optimize the imperfection of ordinary table defects, it brings high-quality products to users. The sense of experience is a kind of spiritual enjoyment, and it is also a perfect improvement for the technology industry.
