Abstract
The invention provides a disk cartridge comprising a flat rectangular parallelepipedal cartridge body , and a disk rotatably enclosed in the cartridge body . The cartridge body comprises opposite side walls formed in parallel to the direction of insertion of the cartridge into a disk player and a front wall facing toward the direction of insertion, and has a shutter slidable along the side wall for exposing the signal bearing surface of the disk . The front wall is in the form of a curved wall or polygonal wall having a central portion formed in the closest proximity to the outer periphery of the disk and opposite side portions formed as retracted toward a direction opposite to the direction of insertion. The front wall thus shaped renders the cartridge body compacted and readily indicates to the user the direction of insertion into the disk player.
