A CD marked with R is a write-once CD (DVD-R, CD-R, etc. ), this is an empty CD with no data at the time of purchase. Users can write data to a CD using a burning CD drive. This data writing process is irreversible, and once written, it cannot be modified or erased.
The optical disc marked RW is a rewritable optical disc (DVD-RW, CD-RW, etc. ). This kind of CD is similar to a write-once CD-ROM. Users can write data with a burning CD-ROM, but the written data can also be modified and erased, which is similar to a U disk (but the erasure life is generally much shorter than that of a U disk).
