Abstract

A magnetic disk apparatus wherein a magnetic member mounted on a bobbin made of a non-magnetic material is disposed at a specific position effective for the full range of movement of a transducer head such that the magnetic member and thus the head is attracted by the leakage flux in a VCM, and the attracting force thus derived has a component that produces a rotation moment in only one direction around the pivot axis of the head to bias the head toward a non-data portion of a data storage disk.
