Scratches on the recording disk caused by sliding of a disk cartridge shutter is prevented by slidably inserting first and second shutters between a tray and a case on the opposite side to a recording disk accommodating portion of the tray. The first shutter simultaneously opens and closes a case side driving shaft insert hole, a case side head insert hole, a tray side driving shaft insert hole, and a tray side head insert hole. The second shutter opens and closes a terminal hole. The second shutter is opened independently of the first shutter and is held in a position so that the case side driving shaft insert hole, the case side head insert hole, the tray side driving shaft insert hole, and the tray side head insert hole are not closed. Closing the first shutter, however, causes the second shutter to also close.
