ABSTRACT:
A recording medium cartridge includes a disc, an inner rotor and a shutter in a shell. Torque is applied to the inner rotor by a coil spring to drive the shutter so as to maintain the closed state of an opening part provided in the shell. When the recording medium cartridge is inserted into a disc device, the inner rotor is rotated against the resilient force of the coil spring by a shutter opening mechanism provided in the disc recording and reproducing device. Thus, the shutter is moved to a position where the opening part provided in the shell is opened. When the cartridge is ejected from the disc device, the inner rotor is rotated by the resilient force of the coil spring to close the shutter.
