ABSTRACT:
A magnetic disk apparatus includes a magnetic disk accommodated for rotation in a housing, a spindle mechanism for driving the magnetic disk to rotate, a magnetic head for writing and reading out information onto and from the magnetic disk, a suspension for supporting the magnetic head thereon, an actuator for driving the suspension in order to move the magnetic head in a radial direction of the magnetic disk, and a retraction mechanism for retracting the magnetic head to a particular area on the magnetic disk when the spindle mechanism is rendered inoperative. The magnetic disk apparatus further includes a mechanism provided at a location above the magnetic disk in an opposing relationship to the particular area of the magnetic disk for pressing at least one of the magnetic head and the suspension against the magnetic disk. In lieu of the pressing mechanism, a displacement restriction member may be provided.
