摘要： 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.

摘要： 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.
