Abstract: A disk drive 10 has at least one disk 16 for data storage. A head 30 supported by an actuator 32 is used for data transfer with the disk. The head is returned to a landing region 26 on the disk when the disk drive is not in operation. The actuator is then locked to retain the head there and prevent accidental loss of data from the disk. Actuator lock 62 includes a latch 68 which cooperates with a notch 60 in the actuator, and a vane 70. Air flow generated by the rotation of the disk causes a pressure on the vane which acts to release the latch. To ensure that sufficient air flow pressure is generated to release the latch, thereby unlocking the actuator, the disk is initially rotated at a high speed. Once the actuator has been unlocked, the disk rotation speed can be reduced to that used in normal data transfer operations.

Abstract: PURPOSE:To separate a lock member without increasing the thickness and weight of a disk device by increasing the rotating speed of a disk driving motor for a prescribed time after a power source is applied, and releasing the lock of an actuator by increasing an air flow force by the rotation of a disk. CONSTITUTION:A magnetic hard disk 16 is turned at speed higher than that in a write or readout operation by a microprocessor, etc., provided with a timer means, etc., for the prescribed time after the power source is applied. Thereby, the air flow force A functioning on a wing 70 can be increased compared with a bias force B applied on the wing 70 interlocking with the lock member 68 and placing a head 30 in a landing area 26 by locking the actuator 32. And the member 68 is separated via the wing 70, and the lock of the actuator 32 by the member 68 is released, and the head 30 can be moved to a data recording area 22, thereby, the separation of the lock member can be performed without increasing the thickness and the weight of the disk device.
