Abstract:
A disk apparatus, comprising:a disk in which information is recorded; a carriage arm having a head slider provided at a tip thereof, said head slider moving over said disk during a read/write operation and being placed at an evacuated position outside an area of said disk during a halt of said disk apparatus; a support base; and an inertia latch mechanism which slides on said support base from an original position to a latch position in response to an impacting force so as to latch said carriage arm when said disk apparatus is impacted, and slides on said support base from the latch position to the original position by disengaging from said carriage arm after dissipation of said impacting force, wherein said support base and said inertia latch mechanism are in contact with each other through at least one raised portion that prevents a single surface-to-surface contact from being dominant between said support base and said inertia latch mechanism.
