Disc drive inertia latch with a wind vane

摘要

A latch apparatus for use in a disc drive includes a pivot portion adapted to be rotatably mounted in the disc drive, such that the pivot portion is rotatable between latched and unlatched positions. A latch arm attached to the pivot portion is adapted to restrict movement of an actuator arm when the pivot portion is in the latched position and is adapted to avoid restricting movement of the actuator arm when the pivot portion is in the unlatched position. The latch apparatus also includes a biasing mechanism attached to the pivot portion. The biasing mechanism is adapted to continually bias the pivot portion toward the unlatched position when the pivot portion is mounted in the disc drive. A wind arm attached to the pivot portion is positioned so that a wind produced by spinning the data storage disc pushes against the wind arm and thereby biases the pivot portion toward the unlatched position when the pivot portion is mounted in the disc drive.
