Abstract

An apparatus for minimizing damage to a disc drive (100) during a non-operational mode while maximizing recording capacity of the disc drive (100) has an actuator assembly (110) with a controllably positionable head (118) supported over the disc during operation. A ramp load assembly (130) is disposed adjacent the disc and has a moveable ramp portion (134) which is extended over the disc during the non-operational mode to support the head and is retracted to a position beyond an outer diameter of the disc during the operational mode. The ramp load assembly (130) is further provided with a latch arm (152) which latches the actuator assembly (110) and a snubber portion which limits deflection of the disc in response to application of a mechanical shock to the disc drive during the non-operational mode.
