摘要： Embodiments of the invention secure a sufficiently large magnetic field, and deter a protrusion phenomenon of a perpendicular magnetic recording head, causing a problem in implementing a low flying height, while solving problems such as erasure of information in peripheral tracks. In one embodiment, a main pole or a stacked body made up of the main pole, and an auxiliary pole is deposited over an underlayer formed on a substrate so as to be in contact with the underlayer. On top of the main pole or the stacked body, there is deposited a coil, a return pole, and a read element in that order, thereby fabricating a perpendicular magnetic recording head. Further, an additional structure may be added such that an underlayer containing a metal is disposed between the substrate, and the main pole or the stacked body made up of the main pole, and the auxiliary pole, and a heat diffusion layer is disposed between portions of the coil and the substrate, or portions of the coil is disposed closer to the substrate than other portions of the coil.

摘要： Embodiments in accordance with the present invention provide a thin-film head formed on an AlTiC substrate of a magnetic head slider. A thin-film head include a write element, a read element, a heater, an alumina insulating film that separates the elements and heater from one another, electric wiring films leading to the respective elements, and an alumina protective insulating film that protects all the layered films. For this configuration, in order to maximize a change in a flying height caused by heat dissipated from the heater and minimize a change in the flying height caused by heat dissipation derived from a recording current, the write element is first formed on the AlTiC substrate and the read element is formed on the write element. An adiabatic layer made of a material exhibiting low thermal conductivity may be formed between the write element and the read element and heater.
