摘要： A thermally-assisted recording (TAR) slider has an integrated TAR head and an integrated long laser diode, like an external-cavity VCSEL. The TAR head is integrated with the slider at the trailing end and includes an optical waveguide having a grating coupler oriented in a plane generally parallel to the slider trailing end, and a near-field transducer (NFT) at the slider air-bearing surface (ABS) and coupled to the waveguide. A carrier is attached to the slider front end and supports the external-cavity VCSEL so that the linear path of its output laser beam is directed from the slider front end to the slider trailing end. An optical body is attached to the slider trailing end and has an input surface for receipt of the laser radiation from the laser diode, an output surface for directing the laser radiation to the grating coupler, and at least one reflective surface for turning the laser radiation from the input surface to the output surface.

摘要： A method for controlling the laser texturing of a magnetic disk by using a texturing laser system to create texturing bumps and an analyzing laser system to determine texture bump height and to provide feedback to the texturing laser system. From an angular distribution of an array of diffracted light intensities of the texturing bumps, the intensity of a first diffraction peak (Int1) and its array position (P1) are determined and utilized to calculate the average bump height h according to the equation: h=A/P1+B(Int1)+C where A, B and C are constants that are determined for a batch of disks by taking a representative sample of disks and texturing them with differing laser energies within the energy level range.
