Patent
CA 2010812
In a disk cartridge of the invention, a lubricating polymer film as a resin in which a solid lubricant or a reinforcing material is dispersed is arranged in a case near the center hole of a disk. Since this lubricating polymer film is hardly abraded even with a disk whose number of revolutions per unit time is high, almost no dust is generated. Therefore, a disk cartridge with higher reliability can be provided.
