Abstract
A mechanical linkage within a computer disk drive is used to ensure that the disk drive heads are parked prior to diskette ejection. An eject frame moves with respect to the chassis and drives a latch in an arcuate path. The latch engages an actuator and drives the actuator to an inner diameter position. The mechanical linkage ensures that the actuator is captured in its parked position whenever the eject frame is in an ejected position. The latch is returned to a stowed position when a diskette is installed in the disk drive. The mechanical linkage protects the heads by ensuring proper clearances from the diskette, and by positioning the actuator in a structurally rigid portion of the receiver plate. The invention has particular applicability to disk drives for portable computers.
