Abstract
A disk cartridge is provided in which if the width of the disk cartridge is W1 and the outside diameter of the disk is D1, then W1 is about the same as D1. Inside the disk cartridge is a disk space in which the disk can rotate. A movement restricting portion restricts movement of the disk in the direction parallel with a disk surface. A cutout that extends through into the disk space is provided in part of a surface forming the width of the disk cartridge. A protrusion is provided in the surface adjacent to the surface in which the cutout is provided and at a position near the cutout.
