ABSTRACT:
A magnetic disk cartridge comprising a disk shell, formed by a pair of shell halves each defining an inner surface in which a magnetic disk is incorporated such that the magnetic disk can rotate, and a liner applied to the inner surface of at least one of the shell halves of the disk shell, which inner surface is disposed facing the magnetic disk. A plurality of recesses and protruding portions are formed in a liner applying region of the inner surface of the disk shell, and the liner is applied to the inner surface of the disk shell such that the liner may be adhered at least to positions in the recesses and pulled by the protruding portions. The magnetic disk cartridge has no risk that the liner becomes slackened even when ambient conditions change, and the weight of the disk shell is kept light.
