    • After the power supply of a disk drive that uses a head to write data at any position on a disk or read data written at any position is turned on, the first initial conditions for the disk drive that are needed to receive a command from outside and execute the command are determined. The disk drive is then brought to a state in which it can receive the command but the spindle motor is not started. After the disk drive is brought to the state in which it can receive the command, the spindle motor is started and the second initial conditions including all initial conditions other than the first initial conditions are determined. Moreover, a control method for a disk drive that is implemented in the above disk drive is disclosed.
    • 在使用磁头写入数据在磁盘上任何位置或读取写入任何位置的数据的磁盘驱动器的电源被打开后,从外部接收命令所需的磁盘驱动器的第一个初始条件 执行命令确定。 然后,磁盘驱动器处于可以接收命令的状态,但是主轴电机未启动。 在磁盘驱动器进入可以接收命令的状态之后,启动主轴电机,并且确定包括除了第一初始条件之外的所有初始条件的第二初始条件。 此外,公开了一种在上述磁盘驱动器中实现的用于磁盘驱动器的控制方法。

    • An access control apparatus includes a memory and a command executor executing an access process on a command with the command completion time limit. An address of an inaccessible recording area is stored in the memory. Data attempted to be written on the inaccessible recording area is obtained. The data is stored in association with the address in the memory. An automated alternate processor executes the automated alternate process of the inaccessible recording area in a predefined period of time after the process executed by the command executor is completed. A memory updater deletes the address of the inaccessible recording area whose automated alternate process has succeeded and the data attempted to be written in the recording area at the address.
    • 访问控制装置包括存储器和执行对命令完成时间限制的命令的访问处理的命令执行器。 无法访问的记录区域的地址存储在存储器中。 获得尝试写入不可访问的记录区域的数据。 数据与存储器中的地址相关联地存储。 自动替换处理器在命令执行器执行的处理完成之后的预定时间段内执行不可访问的记录区域的自动替代处理。 内存更新器删除自动替换进程成功的无法访问的记录区域的地址,并且尝试将数据写入地址的记录区域。
