リツジ。 In a magnetic disk cartridge, a magnetic disk fixed to a flange part of a center core consisting of a shaft part into which a drive shaft is inserted and a flange part is rotatably housed in a disk case. An open gap is formed, and the center core body is integrally molded from plastic mixed with a magnetic substance, while an elastic body for pressing the drive shaft against the inner surface of the shaft portion of the center core body is formed in the upper core. The core is molded from plastic with no magnetic material mixed in, and the upper core is fixed to the center core body by inserting a magnetic disk into the center core body, and the elastic body formed on the upper core is molded into the center core body. A magnetic disk cartridge characterized in that the magnetic disk cartridge is located near the inner surface of the shaft portion of the cartridge.
