ABSTRACT:
In a disk cartridge, wherein a disk is accommodated in a cartridge, a first rack and a second rack are so provided as to be movable along respective sides of the cartridge, which are perpendicular to each other, a transmission mechanism links the first rack with the second rack, a shutter is secured to the second rack, and at least recording head or reproducing head insertion openings of the cartridge are opened and closed by the shutter as the second rack is moved by the first rack, the transmission mechanism comprises an eccentric pin provided on a first pinion meshed with the first rack, a second pinion meshed with a third rack fixed to the cartridge and the second rack, and a rod connecting the eccentric pin with the shaft of the second pinion, so that the stroke of the shutter can be made much larger without changing the stroke of the first rack or the size of the cartridge.
