What is the meaning of CD RW?

a, rewritable discs.

Due to the use of phase change technology, the laser reflectivity of CD-RW platters is much lower than that of ordinary CD discs. Therefore, when CD-RW was first introduced, CD-RW discs could not be read out on regular CD-ROM drives. However, with the advent of MultiRead technology, this problem was quickly solved, and now the use of MultiRead technology has become a must-have for CD-ROM drives.

Any CD-RW drive with MultiRead technology can read CD-RW platters. CD-ROM drives introduced after the end of 1997 all use MultiRead technology. Due to the early development of technology, now CD-R CD-RW drives have a variety of mature and advanced functions of CD-ROM drives, which are well compatible with all kinds of CD-ROM discs and CD-R CD-RW discs.

These platters are no problem to read in a cd-r cd-rw drive.

a This depends on which letter it is abbreviated.

r stands for read; w stands for write, i.e. disc a, which can be read and written

CDs cannot be burned. It can only be read by *** and cd, and ROM is the abbreviation of readonlymemory, which means that it can only be read but not written.

Only optical drives such as CD-R W have the function of writing, that is, they have the function of burning.

w stands for write

Abbreviation for Compact Disk.

2. CD-RW development.

In early 1996, Ricoh, Phlips, Sony, Yamaha, Hewlett-Packard, and Mitsubishi Chemical established an industry forum and released the CD-RW format. The standard was developed by RICOH and in 1996 the industry's first CD-RW driver, model MP6200S, was a product with 2x the burning speed, 2x the speed of copying, and 6x the speed of reading.
