Ramp member of variable inclination angle in recording disk drive

摘要

First and second guiding passages are defined in a ramp member. The first guiding passage extends along a first inclined plane intersecting with a reference plane by a first inclined angle. The second guiding passage extends along a second inclined plane intersecting with the reference plane by a second inclined angle larger than the first inclined angle. The first guiding passage serves to prevent collision between a recording disk and a head slider in a recording disk drive. The second guiding passage serves to enable a short-distance movement of the head slider on the ramp member. The boundary of a data zone can be located closest to the outer periphery of the recording disk.
