摘要： An optical recording head including a media heating device to write and read data to a heat sensitive optical media disk. The media heating device includes an optical energy resonant cavity that produces a high intensity near-field optical spot of subwavelength dimension. Optical energy is coupled into the resonant cavity through a waveguide that is placed proximate the cavity, and optical energy is coupled out of the cavity through an aperture that is placed proximate an antinode or post within the cavity. In reading data from the optical media, a photodetector is placed at the end of the waveguide. Optical energy emitted from the end of the waveguide is influenced by the reflectivity of the media data bit, and is interpreted as the data bit signal.

摘要： An inspection system using laser light directed at an off-axis parabolic mirror which focuses the beam on the surface being inspected and also serves as the collector for scattered and specular light returned from the surface is described. Specular and scattered light returned from the surface onto the parabolic mirror is divided into appropriate fields and directed onto detectors. In the preferred embodiment a polarized laser is used in conjunction with a polarizing beam splitter and a quarter-wave plate to route the reflected beam to a detector while allowing the original beam to be directed through the same optics. The parabolic mirror and selected additional components may be commonly mounted on a translatable stage which is moved along a radius of the disk when the optical inspection is being performed. Other components of the system such as the laser can remain in a fixed position. The system of the invention can be used to inspect one or both planar surfaces of the disk by providing duplication of selected components appropriately oriented with respect to the second surface.

摘要： A horizontal cavity, surface emitting laser (HCSEL) with internal polarization rotation is used in thermally assisted recording in hard disk drives. The desired polarization of the laser is accomplished with two beam reflections off of facets within the diode. The facets are formed in a single ion beam etching step. This device can be used in a thermally assisted recording head to produce polarization incident on the disk aligned with the direction of the tracks on the disk.

摘要： A subwavelength aperture includes a plurality of ridges that project from an aperture sidewall into the aperture opening. The ridges may be closely spaced such that the hot spots associated with the ridges are likewise closely spaced and create an elongated hot spot. The subwavelength aperture of the present invention may be adapted for use in a magnetic head of a hard disk drive for improved thermally assisted recording (TAR) of magnetic data bits. Such a magnetic head may include an optical resonant cavity that is fabricated within the magnetic head structure.

摘要： An ohmic contact for a silicon slider body is disclosed. A scanned laser beam locally heats a metal film on the slider body to interdiffuse the metal and silicon while minimizing the total thermal load on the slider body. This localized heating avoids thermal damage to the sensitive magnetic head region on the slider. The native oxide layer on the slider is removed by a sputter etch, followed by deposition of a diffusion layer. A capping layer is then deposited to reduce oxidation during subsequent processing. The metal layer is then locally annealed by scanning the laser beam over the target area. Contact resistance of less than 100 ohms is achieved while minimizing the thermal load on the slider body.

By providing an aperture having at least two, orthogonally oriented ridge structures, two or more closely spaced near-field light sources can be generated by controlling the polarization direction of the illuminating radiation. Control of the shape of the aperture, and relative dimensions of the ridge structures allows optimization of the relative intensities of the near-field sources.
