    • PURPOSE: All or part of an application program stored in a memory can be rewritten even after a microcomputer is mounted on a disk drive, since a 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 re-programming of the nonvolatile memory is interrupted due to abnormality. CONSTITUTION: 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 outside.
    • 目的:即使在将微型计算机安装在磁盘驱动器上之后,存储在存储器中的应用程序的全部或部分也可以重写,因为重新启动程序区域不被重写,所以在重新启动程序之后立即重新启动应用程序区域的重新编程 即使非易失性存储器的重新编程由于异常而被中断,也被再次执行。 构成:采用在包括电可擦除可编程非易失性存储器(56)和中央处理单元(51)的集成电路中构成的微型计算机(5),用于控制磁盘驱动器(2)。 存储器(56)将诸如记录信息再现控制程序之类的应用程序存储在应用程序区域(561)中,并且重新启动程序用于在重新启动程序区域(560)中更新应用程序。 处理器(51)通过根据从外部提供的应用程序重写命令执行重新启动程序来重写应用程序的全部或部分。
