-
Defective CDs (e.g., cracked, badly bent, rough edges, scratch, dirty CD condensation)
-
8 cm (3 in) CD accessories (e.g., 8 cm (3 in) disc adapter, sticker, label)
-
Nonstandard CDs (e.g., Diameter/thickness is out of specification)
Specification: 119.7-120.3 mm (4.668-4.692 in) of diameter, 12+0.3 or-0.1 mm (0.047+0.012 or 0.004 in) of thickness

Outline of CD-R and CD-RW

Definition
-
CD-R: The CD-R is a non-rewritable version. Once a section of a CD-R is written, it cannot be erased or rewritten.
-
CD-RW: The CD-RW is a re-writable version of CD-ROM and the data can be written an unlimited number of times.
-
Since the reflected laser beam amount of a CD-R/RW is less than the reflected laser beam amount of the conventional CD media, the CD
player/changer may not play the CD-R/RW or the sound may jump.
-
Since the recording quality of the CD-R/RWs vary widely, some CD-R/RWs may not play.
