Abstract
A disk drive which includes an automatic parking brake for retaining the driver arm in a predetermined position when power is removed from the disk drive. The brake is mounted externally to the driver arm, reducing the weight of the driver arm. The brake consists of a spring loaded member held in place during operation of the disk drive by a solenoid acting as an electromagnet. When power is cut off, the solenoid releases the member and the spring biases it against the driver arm and forces the driver arm to a parked position.
