After they are written, they can only be read. There are two different kinds of such media: *In some, the hardware prevents multiple writes, examples of such media are the [[CD-R]] and [[DVD|DVD-R]] discs. There is also some kind of computer memory (called [[PROM]]) which can only be written once. *Certain kind of media use a software solution to emulate this [[behaviour]]. Examples are certain kinds of [[ backup tape]]s and [[harddisk]]s that can also have this [[property]]. {{Tech-stub}} [[Category:Storage devices]]
