    Abstract: The media heating device of the magnetic head includes an optical resonant cavity and a nano-pin that produces a high intensity near-field optical beam of sub-wavelength dimension adjacent to the write pole. The cavity is fabricated as a planar thin film structure in layers that are generally parallel to the magnetic pole thin film layers of the magnetic head, such that a principal axis of the resonant cavity is parallel to the air bearing surface (ABS). Optical energy is coupled into the resonant cavity through a waveguide that is placed proximate the cavity, and optical energy is coupled out of the cavity through a nano-pin that is disposed between the resonant cavity and the ABS.

    Abstract: An apparatus, system, and method for measuring thermally induced electric resistance changes in thermally assisted magnetic recording are disclosed for monitoring laser light output in thermally assisted magnetic recording disk drives. An electrical lead is coupled to a read/write head element. A first electrical resistance in the read/write head element is measured. The read/write head is heated by a laser and a second electrical resistance in the read/write head element is measured. The electrical resistance may be monitored at regular intervals when the read/write head element is on the ramp or the electrical resistance measurements may be continuously monitored as the read/write head flies over the magnetic media.
