Magnetic head and storage medium drive
摘要:
A thin film magnetic head has first and second magnetic poles spaced from each other at a medium-opposed surface. A magnetic pole end layer is opposed to the second magnetic pole in a space between the first and second magnetic poles. A magnetic piece or pieces are interposed between the magnetic pole end layer and the first magnetic pole. A non-magnetic material fills a space between the magnetic pole end layer and the first magnetic pole along the medium-opposed surface. The non-magnetic material contributes to a reduction in the volume of a magnetic body between the magnetic pole end layer and the first magnetic pole. The flux path of the magnetic flux can be narrowed. The narrowed flux path contributes to a reduction in the inductance of the magnetic head. A reduced inductance enables a reliable high-frequency recordation.
