Abstract: A thin film magnetic head includes a recording and playback element, a lead conductor layer for feeding a power to the recording and playback element, an electrically conductive bump for conductively connecting the lead conductor layer to an electrode pad for external connection, and an insulating protective layer filling between the recording and playback element and the electrically conductive bump. A thermal deformation-preventing layer composed of a material having a thermal expansion coefficient smaller than that of the insulating protective layer is disposed in the insulating protective layer in such a way as to locate between a medium-facing surface and the electrically conductive bump without being exposed at the medium-facing surface. In the resulting thin film magnetic head, protrusion of the recording and playback element toward the recording medium side can be prevented without changing the configuration of the recording and playback element nor the forming material.

Abstract: First and second magnetic layers of a magnetic head face each other. A toroidal coil layer having upper and lower layer coil pieces (ULCP and LLCP) is wound around one of the magnetic layers. The ULCP extend from a first insulating layer by downward steps to a top of a second insulating layer which is widened at ends of the first insulating layer. Side ends of the first insulating layer extend parallel to a height direction. The ULCP are orthogonal to the side ends. Each of the LLCP is formed on a third insulating layer and has a straight region extending in the same direction as the upper layer coil pieces and a curved region curved toward a facing surface or in a height direction on one end in the track width direction. An end of each of the straight and curved region is connected to an ULCP.
