Disclosed is an inertia latch mechanism capable of omitting erection of a pin for swinging an inertia lever. An inertia lever for use in the inertia latch mechanism is constituted of: a lever body swinging by inertia when an impact is applied thereto; a fixture fixed to a case of a disk drive device; and a plate spring member for connecting the lever body and the fixture and permitting swing of the lever body.

A disk drive device includes a recording medium, a head slider having a head element for recording data on the recording medium and for reading data recorded on the recording medium, a spindle motor for rotating the recording medium, and a clamp for applying a pressing force to the recording medium to fasten the recording medium to the spindle motor. The disk drive device has a feature in which a film body formed from a material which is more pliable than a material forming the clamp is interposed between the clamp and the recording medium. Even if the clamp does not have a high flatness, the film body absorbs irregularities of the clamp. Thus, it is possible to fasten the recording medium with the clamp while apparently keeping flatness.

The present invention provides an improved magnetic data storage and retrieval system, which can absorb external shock and is easily attached to a host system. By setting bumpers in the four corners of a magnetic data storage and retrieval system, external shock can be absorbed to prevent a magnetic disk from being displaced from the proper alignment with its spindle motor. With this arrangement, in the two corners on the end portion side of a guide groove formed in the base, pedestal surfaces are formed in one side of the guide groove, and plate-like bumpers and are set on the pedestals. Further, in the remaining two corners, insertion-type bumpers may be set and a label covering part of them may be affixed.
