Magnetic head and information storage device

Abstract

According to one embodiment, a magnetic head includes a magnetic pole layer including a magnetic pole extending along a layer, a coil layer configured to adjoin the magnetic pole layer and including a plurality of conductor patterns constituting a part of a coil wound around the magnetic pole and a resin which fills up a gap between the conductor patterns, a heater layer configured to adjoin the coil layer and including a heater extending in the heater layer via an area along a coil-forming region in which the conductor patterns in the coil layer are formed and an area along a no-coil region off the coil-forming region, and a transition-reluctant portion in that part of the no-coil region which adjoins the heater and having a glass transition temperature higher than that of the resin or not having any glass transition temperature.

Dependencies are inferred from the claim text.
