  • Patent number: 8848315
    Abstract: A method for forming a magnetic write pole with a trapezoidal cross-section is described. The method consists of first forming a magnetic seedlayer on a base followed by depositing a removable material layer on the seedlayer, and then a resist layer on the removable material layer. A trench is then formed in the resist, and the resist is heated to cause the cross -sectional profile of the trench to assume a trapezoidal shape. The resist is then capped with another resist layer and further heated to cause the width of the trapezoidal trench to become narrower. The cap layer and removable material layer at the bottom of the trench are then removed and the trench filled with magnetic material by electroplating. The resist and seedlayer external to the trench are finally removed to form a write pole with a trapezoidal cross-section.

  • Publication number: 20130108212
    Abstract: Light is excited by a light source in a first waveguide mode. The light is converted to a second waveguide mode via a channel waveguide having a cross-sectional geometry normal to a direction of propagation of the light that rotates a polarity of the first waveguide mode to a second waveguide mode. The light in the second waveguide mode is delivered to a near-field transducer that provides electromagnetic heating for a heat assisted magnetic recording write head.
