Patent ID: 7602586

Claim:
A head parking ramp for a data storage device to park a read/write head at a position out of a disk, comprising: a fixed portion fixed to a base member; 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 plurality of flat buffer protrusions having a first end secured to the extended portion and a second non-secured end, the flat buffer protrusions having an inner surface closest to each of the upper and lower surfaces of the disk and an outer surface closest to the disk facing surfaces, wherein the outer surface extends from the first end to the second end substantially parallel to the disk facing surfaces and the inner surface extends from the first end to the second end at an incline with respect to the upper and lower surfaces of the disk, the flat buffer protrusions being arranged between the disk facing surfaces of the extended portion and the edge portion of the disk to be separated a specified distance from each of the disk facing surfaces and the disk and restricting a vibration of the disk and absorbing an impact by allowing the edge portion of the disk to contact the buffer protrusions when the disk vibrates.
