    • 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。
