Abstract
A disk cartridge and a disk recording and/or reproduction apparatus including a protrusion group which is made up of a plurality of protrusions and formed within a case 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 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.
