Patent ID: 7151644

Claim:
A magnetic disk apparatus, comprising: a magnetic disk rotationally driven by a rotation mechanism; a magnetic head slider mounted on an arm suspension assembly so as to be movable in a radial direction of the magnetic disk while flying on a surface thereof; a controller for controlling a position of the magnetic head slider in the radial direction of the magnetic disk; and an load/unload mechanism for one of loading the magnetic head slider from a ramp portion onto the magnetic disk and unloading the magnetic head onto the ramp portion; wherein the magnetic disk includes a track and comprises: at least a load zone of a predetermined length in a peripheral direction thereof for performing loading of the magnetic head slider on a surface of the magnetic disk utilizing the load/unload mechanism; a specific pattern recorded in front of the load zone in the peripheral direction thereof; and a data zone provided in front of the specific pattern in the peripheral direction thereof; and wherein the controller reads out the specific pattern recorded on the magnetic disk utilizing the magnetic head slider, and controls the position of the magnetic head slider so as to move the magnetic head slider while avoiding the load zone.
