Abstract
Writer head products for heat-assisted magnetic recording devices and methods of making the same are disclosed. The writer heads include multiple layers including a waveguide blocking layer, a waveguide layer, a near-field transducer layer, a heat sink layer, and a peg layer. Each of the layers may comprise a tapered angle near an air-bearing surface. The writer heads further include a main magnetic pole adjacent to the optical component including the same tapered angle near the air-bearing surface.
