Abstract
A head loading and parking apparatus for a disk drive device is disclosed that is characterized by varying a voice coil current and voltage during a head loading process. The varying voltage nudges read-write heads off of a load ramp and onto the surface of a data storage medium. Peak power is controlled by selectively turning off portions of the electronic system.
