Abstract
A head parking ramp for a data storage device includes a fixed portion fixed to a base member, a support portion extending from the fixed portion toward the disk and supporting an end portion of an actuator where the read/write head is installed, an extended portion extending from the fixed portion toward the disk, having a lead end portion overlapping each of an upper surface and a lower surface of an outer circumferential portion of the disk, and having a plurality of disk facing surfaces facing each of the upper and lower surfaces of the disk, and a protruding surface protruding from each of the disk facing surfaces of the extended portion at a position corresponding to an edge portion of the disk and restricting a vibration of the disk as the edge portion of the disk contacts the protrusion surface when the disk vibrates.
