Abstract
According to one embodiment, a magnetic head includes a write element, a read element, and a heating element disposed between the write element and the read element. When power is applied to the heating element, either the read element or the write element projects beyond a plane of an air-bearing surface (ABS) of the magnetic head, and when power is not applied to the heating element, a portion of the ABS of the magnetic head facing a magnetic disk close to the heating element has a concave shape. In another embodiment, when power is applied to the heating element, at least one of a portion of the read element and a portion of the write element approaches a magnetic disk, and when power is not applied to the heating element, a portion of the ABS of the magnetic head facing a magnetic disk close to the heating element has a concave shape.
