Abstract

A magnetic disk cartridge including a flexible magnetic disk, a hub, disk-holding protrusions, and an anti slip-out member. The hub has a disk-holding surface on which the central portion of the magnetic disk is held. The disk-holding protrusions are formed on the disk-holding surface of the hub, and are inserted through holes formed in the magnetic disk. The anti slip-out member is used to prevent the magnetic disk from slipping out from the disk-holding protrusions.
