ABSTRACT:
A magnetic disc apparatus comprises a base, a disc driving assembly and a head positioning assembly. The head positioning assembly is provided at the bottom portion thereof with a fitting recess and the base is provided at a top surface thereof with a corresponding projection, which, when the head positioning assembly is correctly aligned, fits into the recess in the head positioning assembly. By fitting the fitting projection into the fitting recess, the head positioning assembly is automatically positioned accurately on the base in a predetermined relational position with respect to the disc driving assembly, whereby the pivot axis of the head positioning assembly is positioned in a predetermined positional relationship with respect of the center shaft of the disc driving assembly.
