A disk apparatus includes a disk in which information is recorded, a carriage arm having a head slider provided at a tip thereof, the head slider moving over the disk during a read/write operation and being placed at an evacuated position outside an area of the disk during a halt of the disk apparatus, a support base, and a inertia latch mechanism which slides on the support base from an original position to a latch position in response to an impacting force so as to latch the carriage arm when the disk apparatus is impacted, and slides on the support base from the latch position to the original position by disengaging from the carriage arm after dissipation of the impacting force, wherein the support base and the 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 the support base and the inertia latch mechanism.
