| description | A magnetic disc apparatus including a sealed module which encloses magnetic discs, magnetic heads attached to head arm assemblies, an electromagnetic actuator for positioning the magnetic heads on the head arm assemblies, and a drive spindle on which the discs are seated. All control of the positioning of the head arm assembly, the operation of the electromagnetic actuator and the read write function being provided by electrical signals communicated between the file housing and the sealed module. A drive motor within the file housing is coupled to the enclosed spindle, which extends from the module while maintaining the module seal, for providing only rotary motion to the discs attached to the spindle. |
