  • Patent number: 9159339
    Abstract: A magnetic device includes a write element having a write element tip that defines a medium confronting surface. The write element is operable to generate a first field at the medium confronting surface. A conductor is proximate the write element tip and first and second conductive leads are connected to the conductor and configured to deliver a current to the conductor to generate a second field that augments the first field. First and second side elements are disposed on opposite sides of the write element tip in a cross-track direction at the medium confronting surface. At least a portion of the first conductive lead is disposed adjacent the first side element on a side opposite the medium confronting surface, and at least a portion of the second conductive lead is disposed adjacent the second side element on a side opposite the medium confronting surface.

  • Patent number: 9147415
    Abstract: The present invention generally relates to a HAMR head having not only a tapered core for the SSC, but additionally a secondary confinement material in the cladding surrounding the core taper. The secondary confinement material prevents diverging light from the laser diode from spreading so that the light is coupled into the core of the SSC. The secondary confinement material is a symmetric structure that surrounds the core of the SSC on all sides so that high conversion efficiency is achieved for short taper lengths.

  • Patent number: 8854930
    Abstract: Techniques for improving the recording quality during heat assisted magnetic recording (HAMR) by monitoring the power of a source used to heat a storage medium are described. In one example, a source emits electromagnetic radiation. A waveguide transmits the electromagnetic radiation onto a surface of a magnetic media. A photoresistive material is proximately located to the waveguide. The resistance of the photoresistive material varies based on the intensity of electromagnetic radiation propagating through the waveguide. The power of the source is determined by measuring the resistance of the photoresitive material. The power of the source is adjusted based on the determined power.
