A ramp loading unit, for use in a disk drive that includes a head and a record carrier, that includes a holding part that holds a head support part apart from the record carrier. The ramp loading unit also includes a sliding part which the head support part elastically contacts. The sliding part includes a patterned sliding surface with a protruding part that has a width that can partially contact the head support part, wherein the position of the protruding part changes in the width direction of the sliding surface along the length direction of the sliding surface orthogonal to the width direction, so that a contact position of the head support part with the protruding part changes as the head support part slides on the sliding part in the length direction of the sliding surface.
