ABSTRACT:
A magnetic disk drive apparatus includes a data storage medium, a magnetic head, an arm assembly, and a magnetic head retracting mechanism. The arm assembly includes a voice coil motor for driving the magnetic head. The magnetic head retract mechanism includes a lifter for moving the magnetic head from an area over the data storage medium in a first start/stop mode or a head load/unload mode and a retract magnet constantly urging the magnetic head towards a contact start/stop zone on the data storage medium in a second start/stop mode or a contact start/stop mode. When the data storage medium starts or stops its rotation, the magnetic head retracting mechanism makes use of a head load/unload mode wherein the data storage medium is caused to be started or stopped while the magnetic head is retracted and separated from the data storage medium, and also makes use, in combination therewith, of a contact start/stop mode wherein the data storage medium is caused to be started or stopped while the magnetic head slides on the data storage medium. Since the two modes are used in combination, this makes it possible to avoid the problems arising from the repeated starts/stops of the medium necessitated by the employment of the semi-stop mode and also makes it possible to reduce the power consumed during the starting of the medium.
