Abstract: In a recording system (1), a personal computer (20) reads out boot information from an optical disc (31) in a predetermined order and records elements of the boot information in contiguous areas on the optical disc (32). In order to thus operate, the personal computer (20) refers to access records before reading out the boot information from the optical disc (31). The access records are generated by a protocol analyzer (11) at a start-up of a personal computer (10). Further, for each of the elements indicated by the access records, the personal computer (20) records, on the optical disc (32), an address conversion table in which that area on an optical disc (31) in which the element is recorded and that area on the optical disc (32) in which the element is recorded are correlated with each other.

Abstract: 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.
