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.
Claims20
A method for manufacturing a write head, the method comprising:
- forming a triangular layer with a tapered edge;
- disposing a waveguide (WG) layer adjacent to the triangular layer, the WG layer including a flat section and a tapered section, the tapered section including a tapered angle and contacting the tapered edge of the triangular layer;
- positioning a cladding layer adjacent to the WG layer;
- and
- disposing a near field transducer (NFT) layer positioned adjacent to the cladding layer wherein the NFT layer includes a tapered section that includes the tapered angle.
