What does CD-RW mean?

CD-RW stands for Compact Disc- Rewritable. This is a compact disk that can be modified as required. In CD-RW, the user can do changes like reading, erasing, writing, and rewriting the data. CD-RW came into existence in 1997.

Functionalities

• In CD-RW, the sensitive laser optics technique is used.
• In the manufacturing of CD-RW, the technology of phase change is used.
• CD-RW comes with a minimum writing speed for the disc. 
• The writing speed is highly dependent on external factors like heating or cooling of the disc and the requirement of levels of laser energy etc.
• CD-RW and CD-R contain similar layers of media.
• CD-RW can be reused after the deletion of its preliminary data. 

Two methods can erase CD-RW:

• Full blanking: By this method, all the data consisting in CD-RW is deleted. This method of clearance takes time.
• Fast blanking: Only the metadata, such as pregap, program memory area, etc., is deleted. Fast blacking is very quick and gives enough free space in the disc for further use.

The data distribution in CD-RW is done in the following way:

• System User Area: This area of CD-RW contains the collective data of the power calibration area and program memory area.

• Program Memory Area: This area has the data records which is unfinished. The data of the program memory area is taken as a transition when the session of the disc is not closed.
• Program Area: This area accommodates the data files and audio tracks.
• Power Calibration Area: This part of CD-RW determines the correctness of the laser power of the disc.

Difference between CD- RW, and CDR

• CDR is the disc that can be written once, and then it becomes a readable disc only. While, in CD-RW, one can write, erase, and then rewrite the data several times.
• CD-RW is much more convenient to use than CDR.
