イスクカートリツジ。 In a magnetic disk cartridge, a magnetic disk fixed to a flange portion of a center core consisting of a shaft portion into which a drive shaft is inserted and a flange portion is rotatably housed in a disk case. It is integrally molded with mixed plastic to form an open gap in the center core body, and a magnetic disk is inserted into the center core body to fix the upper core to form the center core, and the shaft part of the center core body 1. A magnetic disk cartridge characterized in that an elastic body made of a metal plate or a plastic plate not mixed with a magnetic substance is separately provided so as to press the drive shaft against the inner surface of the shaft portion.
