Abstract:
1. A ramp loading unit comprising: a holding part that holds a head support part at a position apart from a record carrier, the head support part supporting a head that records information in and reproduces the information from the record carrier; and a sliding part which the head support part elastically contacts when the head is to be loaded over the record carrier and the head is to be unloaded from the record carrier, the sliding part including a patterned sliding surface that faces the head support part, and can contact the head support part via a protruding part of the sliding surface, the protruding part of the sliding surface having a width that can partially contact the head support part, wherein a position of the protruding part changes in a width direction of the sliding surface along a 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 can change as the head support part slides on the sliding part in the length direction of the sliding surface.
