Disk cartridge and disk recording / reproducing apparatus

摘要

A disk cartridge (10) and a disk recording/reproducing apparatus including a protrusion group (20) which is made up of a plurality of protrusions (21) and formed within a case (12) for housing a disk or within a housing in which a disk is loaded. Accordingly, the protrusions induce the flow of air generated during the rotation of the disk (13) to serve as a force generated by variations in flow velocity and pressure. Therefore, foreign materials can be effectively removed from the surface of the disk using the flow of air without a separate cleaning apparatus.
