摘要： The invention features a fly height measurement system for measuring fly height of a slider over a storage disc. The fly height measuring system includes a source of light, a slider, a detector module and a processor. The source of light produces light along a light path. The slider includes an objective lens positioned such that light from said source hits the objective lens and is directed toward a surface of a disc. Light propagating from the disc is directed to a detector. The processor estimates the fly height of the slider based on detector module output.

摘要： An optical data storage system that includes an optical source and an optical storage medium. The system includes a plurality of armatures positioned adjacent to the optical storage medium. Mounted on each armature are elements that perform functions such as beam-splitting, beam-shaping, relaying and fine tuning to collectively form an armature-mounted optical coupling system. An optical switch couples the optical source to each of the armature-mounted optical coupling systems. This configuration of an optical data storage system ensures that one optical source can be utilized for a plurality of optical detection systems.

摘要： An optical data storage system includes an optical disc and an armature adjacent the disc. An optical transducer mounted on the arm provides an optical beam output directed parallel to the plane of the disc. An optical actuator mounted on the arm and positioned in the optical beam adjusts the direction of the optical beam and a mirror is positioned to direct the optical beam in a direction perpendicular to the disc and toward the disc. An optical head is positioned at a distal end of the arm and is adapted to couple the optical beam to the optical disc. An arm actuator is coupled to the arm to move the arm relative to the disc and provide coarse positioning of the optical head relative to tracks on the disc. The optical actuator provides fine adjustment of the optical beam between tracks on the disc which are proximate the optical head due to the coarse adjustment by the arm actuator.

摘要： An apparatus and method for providing a tracking error signal in an optical system in which a radiation beam is applied to an optical storage medium having a number of marks formed thereon. A return beam resulting from application of the incident radiation beam to the medium is separated into a first polarization component and a second polarization component. First and second detectors detect the first and second polarization components and generate first and second detected signals therefrom. A tracking error signal is generated from the first and second detected signals, and is responsive to variations in the return beam arising from diffraction of the incident beam from, for example, cross-track edges of the marks on the medium. The marks may be previously-recorded data marks or preformatted tracking marks, and the medium may be a non-grooved magneto-optic medium.

摘要： Apparatus and method for determining an orientation of magnetic domains currently being irradiated by a laser having two orthogonal linearly polarized modes of operation is described. The orientation of the currently irradiated magnetic domains determines which linear polarization mode is currently active and can be used as a readout technique for signals encoded in a magneto-optic medium. This polarization switching technique for the reading stored information is dependent on adjusting the parameters of the extended laser cavity so that excitation of each polarization mode is substantially equally probable. When the parameters of the extended laser cavity are substantially equally probable, then the difference in the attenuation of circularly polarized radiation resulting from interaction with oppositely oriented magnetic domains in a magneto-optic material determine the current polarization mode. To equalize probability for laser excitation in either orthogonal mode, the extended cavity is structured to include regions wherein only one linear polarization mode is present. In the single mode region, the attenuation of associated linearly polarized laser radiation mode can be separately controlled and the presence of laser activity in the associated mode can be easily determined.
