ABSTRACT:
Apparatus for rotating and driving a magnetic disk in which a hub of a magnetic disk is magnetically attracted against a hub support, and a driving pin provided on the hub support is engaged with an engaging hole provided in the disk hub. The hub support has a magnetic attractive surface which is high in magnetic flux density in the vicinity of the driving pin and continuously and gradually lowers in magnetic flux density as a function of distance from the driving pin, so that the magnetic disk can be attracted by an approximately uniform net attractive force over the entire surface of the hub support.
