What is the CD-R?

CD-R is a short form of “CD-Recordable”, meaning recordable CD. In the past, users could only read the data on a CD-ROM. If users wanted to record data onto a CD, they had to ask assistance from a factory and do so in large quantities. With CD-R however, individuals can save data on a CD and produce a format that is exactly the same as that of a standard CD-ROM. But once made, the recorded sections of a CD cannot be recorded over, and due to different materials used, the colors of CD-R vary between gold, blue and green, unlike the silver of a standard CD-ROM .

What is the CD-RW?

CD-RW is short form for “CD- Rewritable”, in other words, a rewritable CD. The special feature of CD-RW is that the recorded sections can be cleared and reused for re-recording. Of course, users cannot rewrite the CD-RW to an infinite number of times. Typically, each CD-RW can be rewritten about 1,000 times.
