ABSTRACT:
An apparatus and method for loading and offloading a read/write head from a load ramp onto a disc are disclosed. The apparatus includes at least a basedeck supporting a spindle motor with an attached disc and an actuator assembly with a read/write head configured for communication with the disc, and a load ramp positioned adjacent the disc and configured for receipt of the read/write head. The actuator assembly includes at least an actuator motor magnet mounted to said basedeck, an actuator body attached to the basedeck and providing a voice coil configured for interaction with the actuator motor magnet, and a bias feature secured to said actuator body and configured for communication with the motor magnet such that when the read/write head is parked on the load ramp, the bias feature mitigates an unintentional engagement of the read/write head with the disc.
