Claims

[Scope of Claim for Utility Model Registration] A disk is rotatably stored in a cartridge, a pair of head insertion holes are provided on both sides of the cartridge, and the head is inserted into the head insertion hole while rotating the disk at high speed within the cartridge. Therefore, in a disk cartridge configured to perform recording or playback on a disk, one of the pair of head insertion holes has a peripheral edge located on the rear side in the disk rotation direction that projects toward the disk side. A barrier portion is provided in the other head insertion hole, and a barrier portion protruding toward the disk side is provided on a peripheral edge located on the front side in the disk rotation direction, and when the disk is rotated at high speed within the cartridge, one of the head insertion holes is provided with a barrier portion protruding toward the disk side. The barrier portion of the head insertion hole prevents air from flowing out from inside the cartridge to the outside of the cartridge, and the barrier portion of the other head insertion hole prevents air from flowing into the cartridge from outside the cartridge. A disk cartridge characterized in that the air outside the cartridge is made to flow into the cartridge from the one head insertion hole, and the air inside the cartridge is made to flow out of the cartridge from the other head insertion hole. .
