A recording and regeneration apparatus for reliably erasing data stored on a disk medium (such as a disk drive) which does not require a particular working environment such as a host system or a medium that stores the dedicated data erasure program. The apparatus comprises a disk medium on which data is recorded, a switch for generating an erasure instruction designating an erasure mode, and a processor for executing a program stored in a memory for erasing data recorded on the disk medium, if the erasure instruction is generated. The erasure instruction may also be generated in response to a command signal external to the apparatus. The processor may determine whether or not the erasure instruction is generated upon application of power to the recording and regeneration apparatus.
