ABSTRACT:
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.
