To prevent erroneous insertion of a recording medium cartridge into a holder in a recording medium drive device simply and without causing a sharp rise of price of the recording medium drive device.A shutter opening piece (32c) for sliding a shutter (110) supported upon a case (101) of a recording medium cartridge (100) to open a light transparent hole (101h) is provided in a holder (8) in a recording medium drive device (6), when the recording medium cartridge (100) is normally inserted into the holder (8), the shutter (110) is slid by the shutter opening piece (32c) to open the light transparent hole (101h), and when the recording medium cartridge (100) is inserted into the holder (8) in an erroneous direction, the opening edge of a function expansion groove (104) of the case (10) contacts the shutter opening piece (32c) to prevent erroneous insertion of the recording medium cartridge (100) into the holder (8).
