Abstract: An apparatus includes a substrate. A laser is deposited above the substrate. The laser includes one or more non-self-supporting layers of crystalline material. The laser has a length along a light path in a range of about 40 um to about 350 um. An optical input coupler is configured to receive light from the laser. A waveguide is deposited proximate the optical input coupler. The waveguide is configured to communicate light from the laser via the optical input coupler to a near-field transducer that directs energy resulting from plasmonic excitation to a recording medium.

CPC classification number: G11B5/315 , G11B5/10 , G11B5/3116
Abstract: A data storage device employing a data writer may configure the data writer with at least a write pole that is separated from a front shield on an air bearing surface. The front shield can be arranged to continuously extend from the air bearing surface a first throat height distal the write pole and a second throat height proximal the write pole with the first and second throat heights being different.

Abstract: A data writer may be generally configured at least with a write pole adjacent to and separated from a side shield and a trailing shield. The side shield may be formed of a first material and configured with a trailing box region that is at least partially filled with a flux density insert formed of a second material that is different than the first material.
