Coaster toaster
Updated: 02/07/2022 by Computer Hope
Coaster toaster is an informal term used to refer to a CD (Compact Disc) or DVD (Digital Versatile Disc) burner that creates defective discs. The name comes from a combination of two phrases. The first part from the fact that the data written to CDs is unreadable, rendering them useless — except possibly as a beverage coaster. The toaster bit is a slang term for an optical disc burner.
