Provided is a thin film magnetic head capable of reducing the amount of protrusion of a write shield layer, thereby preventing a collision with a recording medium, and thereby ensuring a recording operation with stability. A heat sink layer is disposed on the leading side of a thin film coil in order to dissipate heat produced by the thin film coil. When the thin film coil produces heat during the recording of information, priority is given to the guidance of the heat to the leading side of the thin film coil, namely, the side opposite to the position of the write shield layer, rather than the guidance of the heat to the trailing side of the thin film coil, namely, the position of the write shield layer, so as to dissipate the heat. Thus, the thin film magnetic head reduces the likelihood of the heat accumulating in the write shield layer, thus reduces the likelihood of the write shield layer expanding thermally, and thus reduces the amount of protrusion of the write shield layer.

A slider mounted TAMR (Thermal Assisted Magnetic Recording), DFH (Dynamic Flying Height) type read / write head using optical-laser generated surface plasmons in a small antenna to locally heat a magnetic medium, uses the same optical laser at low power to pre-heat the antenna. Maintaining the antenna at this pre-heated temperature, approximately 50% of its highest temperature during write operations, allows the DFH mechanism sufficient time to compensate for the thermal protrusion of the antenna at that lower temperature, so that thermal protrusion transients are significantly reduced when a writing operation occurs and full laser power is applied. The time constant for antenna protrusion is less than the time constant for DFH fly height compensation, so, without pre-heating, the thermal protrusion of the antenna due to absorption of optical radiation cannot be compensated by the DFH effect.
