Abstract

A disk drive includes base with a spindle motor, first and second rockers and first and second sliders. The spindle motor has a turntable to mount a disk. The first and second rockers rock so as to pivot about fulcrums substantially parallel to the turntable. The first rocker pulls in the disk, inserted externally, to a position where the disk and motor have their centers aligned. The second rocker unloads the disk from the position to a point where the disk is exposed partially. The first and second sliders are engaged with the first and second rockers to make them pull in and unload the disk, respectively, and reciprocate substantially parallel to the turntable. The rockers and sliders are located under the turntable. The slider(s) support(s), raise(s) and lower(s) a side face of the base through the reciprocation.
