。 A magnetic disk in which a magnetic disk body is rotatably housed in a container consisting of an upper shell and a lower shell in which a spindle insertion hole is formed, with the hub supported by the metal plate fitted into the spindle insertion hole. The cassette is characterized in that a tapered part is formed on the inner surface of the peripheral edge of the spindle insertion hole of the lower shell, the thickness of which gradually decreases as it moves away from the spindle insertion hole, so that the outer peripheral edge of the metal plate does not come into contact with the outer peripheral edge of the metal plate. magnetic disk cassette.
