Abstract

A latch mechanism for latching the actuator assembly of a disc drive in a parked position. The latch mechanism includes a latch body having a pivot point rotatable upon a pivot pin integrally coupled to the disc drive, the latch body having a center of gravity substantially near the pivot point. The latch body having a moment of inertia, J<SB>L</SB>, which is approximately equal to the moment of inertia, J<SB>A</SB>, of the actuator multiplied by a gear ratio, GR<SB>L/A</SB>, between the latch body and the actuator. The latch body includes a pair of arms, which meet at the pivot point, and a latching section for latching with a latch member attached to one end of the actuator. The latch body also includes a plurality of ferro-magnetic balls attached to each arm. The latch mechanism also includes a magnet coupled to the disc drive, the magnet situated near the pair of arms to attract the ferro-magnetic balls and thus rotate the latch body.
