An optical disc device 60 prevents intrusion of foreign matter such as dust and dirt into a disc cartridge 1 that has a main cartridge body unit 4 for rotatably housing an optical disc 5, apertures 7, 8 for partially exposing a signal recording area of the optical disc 5 and a shutter member 9 movably mounted on the main cartridge body unit for closing the apertures 7, 8. The optical disc device also includes a loading mechanism 76 for loading the disc cartridge 1 across the inside and the outside of the main body portion of the device, a shutter actuating unit 154 for moving the shutter member 9 for opening the recording/reproducing apertures 7, 8 when the disc cartridge 1 is loaded on the recording/reproducing unit adapted for recording and/or reproducing information signals and an optical pickup device 143 for intruding into the disc housing via the recording/reproducing aperture when the shutter member 9 has opened the recording/reproducing aperture.
