Abstract:
1. A thin film magnetic head, comprising: a magnetic transducer film being disposed so that an end surface thereof faces a recording medium, and detecting a signal magnetic field from the recording medium; a heat dissipation layer being disposed adjacent to the magnetic transducer film so as to occupy at least a part of a same layer level of the magnetic transducer film on a side, the side being opposite to the end surface facing the recording medium, and transferring heat generated in the magnetic transducer film to outside; and an insulating layer between the magnetic transducer film and the heat dissipation layer, wherein a portion of the insulating layer in contact with an end surface of the magnetic transducer film on a side, the side being opposite to a side facing the recording medium has a thickness ranging from 2 nm to 30 nm inclusive.
