摘要： A magneto optical head assembly combining a single high extinction polarizing beam splitter utilized to separate and analyze a light beam, a pair of half-wave plates, each having a fast axis with respect to the polarization direction of light transmitted through the head assembly, with the angle of the fast axis of one of the half-wave plates preferably being equal but opposite that of the angle of the fast axis of the remaining half-wave plate. The light beam is transmitted through the head assembly polarizing beam splitter to be polarized with one half of the transmitted polarized light passing through one of the half-wave plates and the remaining half of the transmitted polarized light passing through the other half-wave plate. The portion of the transmitted polarized light which passes through each half-wave plate is rotated about the fast axis of each plate and focused upon a point on a magnetic recording medium. The light is reflected off the magnetic recording medium, with its attendant Kerr rotation, back through the other half-wave plate into the polarizing beam splitting portion of the head assembly. The beam splitter directs a portion of the reflected light beam to a pair of photo detectors. The polarizing output signals of these detectors are coupled into a differential amplifier where the common signal components cancel, leaving only the Kerr rotation signals component which is indicative of the magnetization state of that point on the magnetic recording medium where the light is focused.

摘要： An optical assembly incorporating a wedge-shaped optically transparent prism, a 45 degree right isosceles triangular prism which has two thin film coated surfaces, a rhomboidal prism attached to the triangular prism, a second, smaller 45 degree right isosceles triangular prism attached to one end face of the rhomboidal prism and two planoconvex lenses attached to the combination of the rhomboidal and second triangular prisms is mounted within a housing. All of the optical components are cemented to the adjacent component utilizing a transparent optical cement to form an integral unit. Data and servo detector assemblies and a diode laser light source are mounted on the external surfaces of the housing to form a stationary optical assembly which provides the following functions: generates a collimated beam of light whose power output may be modulated electronically to perform read, write and erase functions; generates an electrical data signal derived from a portion of a returning light beam; and generates suitable electrical error signals for servomechanical control of radial and axial motion of a focused light spot on information storage media.

摘要： When doing multitrack seek or a single track jump, the midpoint between the maximum and the minimum of a tracking error signal is determined. A peak detector detects the positive peak and the negative peak. These maximum and minimum values are stored in a sample and hold circuit. A summing circuit determines the midpoint between the maximum and the minimum of the tracking error signal. An operational amplifier provides a true error signal to the servo control system that provides the appropriate servo operating point. The invention is based on the fact that even though there is no absolute reference signal indicating the appropriate on-track position, the tracking servo system obtains the track error over the whole range of positions relative to track center when doing a multitrack seek or a single track jump. The appropriate servo operating point is the midpoint between the maximum and the minimum of the track error signal. This provides compensation for level shifts due to factors such as beam displacement, or detector mispositioning, changes in read/write beam profile, and disk tilt. The present invention solves the key disadvantage of the continuous groove tracking method by eliminating tracking offsets without adding additional information to the disk. It also avoids imposing overhead on the data channel. It compensates for effects of disk tilt, detector misalignment, detector and amplifier offsets, and beam decentration due to fine tracking.

摘要： An electro-optical storage system based on air-bearing-suspended optical head in a near-field configuration. The optical head effects a lens having front and rear focal planes. The head is spaced from an optical medium by a fraction of a wavelength. An imaging lens is positioned relative to the optical head so that the image of a beam steering element is at a focal plane of the optical head close to the imaging lens to form a telecentric system to minimize beam walk. More preferably, the imaging lens is positioned to deviate the image plane of the beam steering element away from the focal plane of the optical head by a desired spacing to form a pseudo telecentric system to minimize energy asymmetry in the reflected beam.
