Abstract
A thin film magnetic head is provided. The thin film magnetic head includes a first magnetic portion separated from a second magnetic portion in a perpendicular direction. A coil layer is disposed between the first magnetic portion and the second magnetic portion. A slot height determining layer is disposed on a gap layer of the first magnetic portion at a position spaced at a predetermined distance from the opposing surface in a height direction so as to extend in a track width direction. A coil layer is formed at an upper surface of the gap layer in a height direction of the slot height determining layer. A coil insulating layer is formed to cover the slot height determining layer and the coil layer while exposing one end thereof in a height direction of the first magnetic portion.
