Driving mechanism for magnetic hard disc memories

摘要

A driving mechanism for magnetic hard disc memories includes an isolated space for maximum cleanness, a driving motor mounted within the apparatus and having a stator and a rotor, the motor when energized having parts producing magnetic flux, a hub extending into the space of maximum cleanness for receiving therein at least one magnetic hard memory disc, a connection between the motor and the hub for driving the hub, a magnetic flux shield located between the parts producing the magnetic flux and the space of maximum cleanness, and the rotor being detachably connected to the rotor shaft.
