タ。 The head insertion hole into which the read/write head of the disk cartridge is inserted and the rotation hole into which the rotary spindle is inserted are freely opened and closed, and the read/write head is inserted along the longitudinal direction of the head insertion hole of the cartridge. In the shutter of the double-sided disk cartridge, the shutter is formed by bending a single plate from its center to form two opposing closing plate parts, each of which has both holes. An opening window is formed for opening the cartridge, and an elongated guide plate part is formed at the bent part of both of the closing plate parts to engage the front end of the cartridge inserted into the reading/writing device, and one end of the guide plate part is formed. A guide slope is formed on which a disposable pin for opening the shutter is guided, and a notch for inserting the head is formed on both sides in the width direction in a portion of the guide plate portion corresponding to the opening window. Features a double-sided optical disk cartridge shutter.
