    摘要: 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.

    摘要: A hard disk drive slider has an air bearing surface that uses the ambient air in the disk drive as a heat source for thermal-assisted recording. Incoming air between the slider and the disk surface is pressurized to produce heat sufficient to heat the recording media. A very small thermal pad is located at the trailing end of the air bearing surface and wraps around the magnetic recording head. The thermal pad includes small pockets to contain the heated air to provide heat to the recording media. The air can be pressurized to approximately 80 atm, which is sufficient to raise the air temperature to approximately 800 degrees C. at isentropic conditions. The heated air transfers the heat energy to the recording media by conduction to elevate a disk recording layer temperature for thermomagnetic recording.
