Estimating the term…
There is provided an information recording/recording device that can easily modify the respective reproduction control programs and other programs of plural disk drive units simply by mounting an information recording medium in one disk drive unit. One disk drive unit uses predetermined recording information of a mounted information recording medium to rewrite a program stored in a nonvolatile memory of the one disk drive unit, and transfers a program to another disk drive unit over an interface bus to instruct program rewriting. According to the rewriting instruction from the one disk drive unit, the other disk drive unit rewrites a program stored in a nonvolatile memory thereof. If the information recording medium is reproduced in one disk drive unit, program information can be transferred to a different disk drive unit.
An information recording/reproducing device, including:
A computer-readable recording medium in which a first access control program executed by a first CPU for instructing a first disk drive unit to access an information recording medium, a second access control program executed by a second CPU for instructing a second disk drive unit to access an information recording medium, and information for identifying the first access control program and the second access control program are recorded so as to be accessible in one of a CD-ROM disk drive unit and a CD-RW disk drive unit as the first disk drive unit and the second disk drive unit.
A computer-readable CD-ROM medium in which a first access control program for instructing a CD-ROM disk drive unit having a CPU to access CD-ROM media, a second access control program for instructing a CD-RW disk drive unit having a CPU to access CD-RW media, and file identification information of the first access control program and the second access control program are recorded so as to be accessible in the CD-ROM disk drive unit or the CD-RW disk drive unit.
