Abstract: A magnetic sensor includes an MR element and a support member. The support member has an opposed surface including a first inclined portion, and a bottom surface. In a given cross section, the first inclined portion is inclined at a first angle at a first position, and inclined at a second angle smaller than the first angle at a second position. The absolute value of a curvature of the first inclined portion at the first position is less than the absolute value of the curvature of the first inclined portion at the second position. The MR element is provided on the first inclined portion so that the first edge is located above the first position in a given cross section.

Abstract: A magneto-resistive effect element includes a magnetization free layer, an intermediate layer, and a magnetization pinned layer. The magnetization free layer extends along a first plane. The intermediate layer extends along the first plane, and is stacked on the magnetization free layer. The magnetization pinned layer extends along the first plane, and is provided on side opposite to the magnetization free layer with the intermediate layer being interposed therebetween. Here, the magnetization free layer includes an end surface that has a maximum inclination angle of 42° or less relative to the first plane.

Abstract: A microwave assisted magnetic head includes a main magnetic pole; a trailing shield; and a spin torque oscillator provided between the main magnetic pole and the trailing shield. The spin torque oscillator has a first end surface configuring a part of an air bearing surface, a second end surface facing the main magnetic pole, and a third end surface facing the first end surface, the first angle θ1 made by the first end surface and the second end surface is smaller than the second angle θ2 formed by the second end surface and the third end surface, and the second angle θ2 is 80 to 100 degrees.
