Claims

[Scope of utility model registration request]

In a disk cartridge case comprising a cartridge case having a head insertion port at a predetermined position, and a recording disk rotatably housed inside the cartridge case, at least the head insertion port is located inside the cartridge case. A shielding member that introduces airflow generated as the disk rotates from the disk rotation region to the radial outside of the rotation region on the upstream side in the disk rotation direction, and a shielding member that captures dust, etc. floating in the vicinity of the shielding member. A disk cartridge characterized by being provided with a capturing member.
