Recording disk drive and ramp member therefor

摘要

A recording disk drive includes a restriction member located within an enclosure at a location opposed to a slant. The slant is defined on a ramp member so as to get closer to a recording disk at a location closer to the center of the recording disk. The slant is designed to receive the tip end of a head actuator supporting a head slider. If an impact acts on the recording disk drive during the movement of the head slider toward the recording disk or off the recording disk, the tip end of the head actuator tends to jump up from the slant. Here, the tip end of the head actuator is received on the restriction member. The restriction member thus serves to reliably prevent the head slider from jumping up. The head slider is prevented from colliding against the enclosure.
