Abstract
A disc cartridge includes: a disc storage portion; first and second shutters provided on the bottom of the disc storage portion; and a rotational member interlocked with the shutters and having a disc supporting portion to support the disc thereon while the shutters are closed and a notch to be located inside a head opening while the shutters are opened. The shutters include disc holders for holding the disc thereon with the center of the disc offset from that of the disc storage portion such that an outer side surface of the disc contacts with the sidewall of the disc storage portion at a position where the notch is located while the shutters are closed. The inner circumference of a region, where the disc supporting portion contacts with the second side of the disc, defines a circle that has its center offset from the center of the disc storage portion.
