Abstract: PROBLEM TO BE SOLVED: To objectively evaluate dust proof performance of a disk cartridge from the area ratio of foreign particles shown on the surface of an optical disk through the observation of the foreign particles adhering to the optical disk in a state stored in the disk cartridge. SOLUTION: The disk cartridge 1 storing the optical disk 7 is stored in a sealed test container 43 together with dust. The disk cartridge 1 is exposed for predetermined time in a dust atmosphere containing the dust. Then, the optical disk 7 is removed from the disk cartridge 1, and the dust proof performance of the disk cartridge 1 is determined on the basis of the dust adhering to the surface of the optical disk 7.
