Optical disc drive device

摘要

A hybrid BD drive 1 (1) of the present invention includes a flash control section (2) which (a) uses a flash memory (7) as a cache memory in a case where the hybrid BD drive (1) receives an address or data via an interface (13) and which (b) uses the flash memory (7) as a data memory in a case where the hybrid BD drive (1) receives an address or data via an interface (14). This makes it possible to provide an optical disc drive device having a nonvolatile memory capable of reducing an access time in random access and storing data except cache data.
