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.
