ABSTRACT:
A latch for a disc drive, wherein the disc drive has an actuator that is pivotally supported for moving an array of read/write heads radially across a data storage disc between a parked location and a data storage location, the parked location providing a landing surface for the read/write heads when the disc drive is non-operational, the latch limiting the actuator from pivoting so that the read/write heads remain in the parked location while the disc drive is non-operational. The latch has a base member enabling attachment to the disc drive, the base supporting an inner stop and an outer stop which limit the actuator rotation, the base further supporting a cantilevered latch arm which biases a latch finger to a position whereat the latch finger and the inner stop form a latching groove and the latch finger and the outer stop form an unlatching groove, the actuator being confined by the latching groove in the latched mode and being confined by the unlatching groove in the unlatched mode.
