Abstract
A hard disk assembly comprises a hub made of injection molded liquid crystal plastic, to which is mounted a magnetic disk by a twist-lock screw top. The expensive step of machining the critical hub component is avoided because sufficient accuracies can be achieved with the liquid crystal plastic when injection molded.
