After writing to a CD-R, it becomes a CD-ROM. A Compact Disc Re-Writable (CD-RW) is an erasable disc that can be reused. The data on a CD-RW disc can be erased and recorded over numerous times. NOTE: CD-RW media may not be readable outside of the drive it was created in.
Are all CDs rewritable?
Can all drives read CD-RW discs? CD-RW discs have less reflectivity contrast than regular discs, so older CD-ROM drives might not be able to reliably read them. However, almost all regular CD-ROM drives manufactured today, including all multiread drives, will have no trouble with them.
Can CD-ROM be erased?
No. After a CD or CD-R is created, it cannot be edited, erased, formatted, or otherwise modified.

Why can’t you write a CD-R disc more than once?
By creating areas of “burned” dots, and other places where the dye is left alone, a CD-R writer creates a pattern of binary zeros and ones that can be used to store information. Unfortunately, once the dye is “burned” it’s permanently transformed: you can’t change it back again. And that’s why you can only write a CD-R disc once.
Will this disc eventually become unplayable?
This disc will eventually become unplayable. With the invention of CDs, people finally had a more reliable way of collecting music. CD players are neither mechanical nor magnetic but optical : they use flashing laser lights to record and read back information from the shiny metal discs.
What is the original form of computer CD called?
The original form of computer CD was called CD-ROM (CD-Read Only Memory), because most computers could only read information from them (and not store any information on them). In those days, you needed a separate piece of equipment called a “burner” to write your own CDs, which were often called WORMs (Write Once Read Many).
