摘要： A microcomputer (5) constituted in an integrated circuit including an electrically erasable programmable nonvolatile memory (56) and a central processing unit (51) is adopted for controlling a disk drive (2). The memory (56) stores an application program, such as a recorded information reproduction control program in an application program area (561) and a reboot program which is utilized to update the application program in a reboot program area (560). The processor (51) rewrites all or part of the application program by executing the reboot program according to an application program rewriting command supplied from the outisde. Therefore, all or part of the application program stored in the memory (56) can be rewritten even after the microcomputer (5) is mounted on a disk drive. Since the reboot program area is not rewritten, the reprogram of the application program area is restarted immediately after the reboot program is executed again even when the reprogramming of the nonvolatile memory is interrupted due to abnormality.
