Disk cartridge and recording and/or reproducing device

摘要

Disclosed is a disc cartridge in which is housed an optical disc ( 2 ). The disc cartridge includes a main cartridge body unit ( 5 ), rotatably housing an optical disc, and having an aperture for a head part ( 13 ) for exposing a part of the optical disc to outside across the inner and outer rims of the optical disc, and a shutter unit ( 15 ) mounted for movement to this main cartridge body unit for opening/closing the aperture for the head part ( 13 ). A recess ( 31 ) into which is introduced a portion of a head part of the recording and/or reproducing apparatus is formed in continuation to the aperture for the head part in a surface of the main cartridge body unit on which slides a shutter unit in an area opposite to the area of movement of the shutter unit with the aperture for the head part in-between.
