摘要： A silicon nitride self-lubricating layer forms the upper surface of a data storage disk. The silicon nitride self-lubricating layer can replace the carbon protective overcoat and liquid lubricant used in conventional data storage devices in which an aerodynamic slider is supported by an air bearing by providing both physical protection for the underlying recording layer and lubrication between the slider and the disk.

摘要： A head gimbal assembly includes a magneto-resistive read element integrated with a thermally assisted write element. The head gimbal assembly includes an optical waveguide positioned between two write poles to transmit a laser beam to a recording medium. The laser beam heats the medium sufficiently and lowers its coercivity in order to facilitate writing. A laser assembly is attached to a suspension for achieving direct coupling of the laser beam to an input end of the optical waveguide. The laser assembly is produced using cost effective wafer processing techniques. The use of silicon for the mounting block allows it to be used as a heat sink, for conducting heat away from the laser diode and into the suspension.

摘要： A near field optical recording/reproducing head and a near field optical recording/reproducing apparatus using the head that are adaptive for writing an information onto a recording medium and reading out an information written on the recording medium by irradiating a near field light onto the recording medium and converting a near field light reflected the recording medium. In the near field optical recording/reproducing head, a first tip is floated by a minute height from the recording medium to focus an incident light onto the recording medium in a shape of near field light, and a second tip is floated by a minute height from the recording medium to convert a near field light reflected from the recording medium into an electrical signal. A mounting member supports the first and second tips with inclination and symmetrically. First and second minute displacement drivers move the first and second tips within a minute displacement in two-axis direction perpendicular to each other, respectively.

摘要： Light emitted from a light source is converged by an objective lens, and an auxiliary lens increases an effective numerical aperture to project the light on a recording medium. The temperature of a recording mark recording on the recording medium is increased by the projection of the light, and saturation magnetization which is in accordance with the information is generated, thus generating magnetic flux. There is a reproducing magnetic layer, which is provided on the auxiliary lens. Magnetization generated on the reproducing magnetic layer has an effect on the polarization direction of the reflected light at the reproducing magnetic layer. Reflected light from the reproducing magnetic layer reaches a photodetector to generate a reproduced signal.

摘要： A reproducing apparatus reproduces a signal recorded in a magneto-optical disk. The magneto-optical disk includes a layered structure having a recording layer, an intermediate layer and a reproducing layer. Laser light is illuminated from an optical head to the magneto-optical disk in such an intensity that no magnetic domain is transferred from the recording layer to the reproducing layer only by the laser light. In this state, alternating magnetic field is applied through a magnetic head to the magneto-optical disk, thereby concurrently causing transfer and expansion of a magnetic domain to the reproducing layer. As a result, transfer of the magnetic domain is effected with expansion.

摘要： The magneto-optical recording medium has a magnetic domain magnification reproducing layer and an information recording layer. Clock marks are formed on the information recording layer, making it possible to generate a reproducing clock on the basis of these. The clock marks are detected either by irradiating directly with light of wavelength &lgr;2(&lgr;1≠&lgr;2), being different from the light of wavelength &lgr;1 which is used for reproducing the recording marks, or by applying a direct-current magnetic field, transferring and enlarging the clock marks on to the magnetic domain magnification reproducing layer, and detecting the reproduction signals from this magnetic domain magnification reproducing layer. Since the reproducing clock is in exact synchronisation with the recording marks, it is eminently suitable as a clock for pulse-modulated reproducing light and reproducing magnetic fields used when reproducing the reproducing layer.

摘要： A magneto-optical recording medium comprises a protective layer having a self-lubricating property formed at an uppermost layer on a side opposite to a substrate wherein a recording or reproducing light beam comes into a side of the protective layer. The thickness and the refractive index of the protective layer are selected under predetermined conditions depending on whether or not evanescent light is transmitted through the protective layer. It is possible to perform high density recording and reproduction thereof by utilizing the evanescent light. A protective layer having a self-lubricating property may be also formed on a bottom surface of an optical head opposing to the optical recording medium. Even when the optical head contacts with the surface of the optical recording medium, the sliding scratch scarcely occurs, because the optical head smoothly glides on the recording medium surface. It is possible to reduce the influence of multiple interference of light which would be otherwise caused in an air layer existing between the optical recording medium and the optical head, and it is possible to suppress variation in reproduced signal intensity.
