ABSTRACT:
A disk cartridge includes a data storage disk and a casing for accommodating the disk. The disk includes a recoding portion and a non-recording portion. The casing has an inner surface facing the disk. An anti-static layer is provided on the inner surface of the casing for eliminating the static electricity generated on the disk. An elastic member or cushion is provided on the inner surface of the casing. The recording portion of the disk is brought into contact with the anti-static layer only when the disk is not rotating.
