ABSTRACT:
A disc cartridge includes a cartridge body, first and second shutters, and a rotational member. The cartridge body includes a disc storage portion to store a disc in a rotatable state, a chucking hole provided on the bottom of the disc storage portion so as to get the disc chucked externally, and a head access window provided on the bottom of the disc storage portion so as to allow a head, which reads and/or writes data from/on the disc, to access the disc. The first and second shutters are provided so as to expose or cover the head access window by rotating in the disc storage portion. The rotational member is provided so as to rotate in the disc storage portion, too. The first and second shutters are interlocked with the rotational member so as to rotate in mutually opposite directions and at respectively different velocities.
