    摘要: The present invention relates to an optical pick, an optical drive device, and a light irradiation method capable of suppressing a generated amount of shift Δx of a spot position.
    The optical pickup irradiates an optical recording medium through a common objective lens which irradiates a first light for use in information recording in or information reproduction from a recording layer and a second light different from the first light, the optical recording medium includes a reference surface having a reflection film in which a position director is formed in a spiral form or the like form, and the recording layer which is provided in a layer position different from the reference surface and in which a mark corresponding to irradiation of light is formed and hence information is recorded. The optical pickup adjusts a focusing position of the first light having passed through the objective lens by changing collimation of the first light entering the objective lens, thereby suppressing the shift Δx of a spot position between the first light and the second light which occurs due to the eccentricity of the optical recording medium. A magnification of the second light is within a magnification range of the first light.

    摘要: The invention relates to a "jump gap" servo mode provided to position an optical tape medium relative to a pickup head so that tracking may be reestablished after gaps in the servo tracks which occur in the pre- and post-amble fields. These gaps arise periodically because of a seam in the drum used to emboss the servo track on the tape medium. Also disclosed herein are other aspects of optical tape technology, tape manufacturing, and tape usage including: configurations, formulations, markings, and structure of the optical tape; manufacturing methods, systems, and apparatus including curing processes, coating methods, embossing, drums, testing, tracking alignment stamper strip; pick up head adapted for the disclosed optical tape; and optical tape uses including optical storage media devices for multimedia applications.

    摘要: Provided are a method and apparatus for recording and/or reproducing data into and/or from an optical disk (10). The apparatus includes a reference beam optical system (20) to form a focus of a reference beam (Lb1) in an optical data storage layer (13) of the optical disk (10) and including an objective lens (100); a signal beam optical system (50) to form a focus of a signal beam (Lb2) in the optical data storage layer (13) and also including the objective lens (100); and a servo optical system (70) to project a servo beam (Lr1) onto the optical disk (10), receiving a reflection servo beam (Lr2) which is reflected on the optical disk (10), and performing focusing and tracking control on the objective lens (100). The reference beam optical system (20) includes a first focus mover (32) to move the focus of the reference beam (Lb1), and the signal beam optical system (50) includes a second focus mover (58) to move the focus of the signal beam (Lb2). The data is recorded into a plurality of recording layers in the optical data storage layer (13) by moving a first focus position (Fb), at which the foci of the reference beam (Lb1) and the signal beam (Lb2) are located, in a thickness direction of the optical data storage layer (13), which is a focusing direction.

    摘要: In an information recording medium comprising at least a substrate, a recording layer, and a resin layer, the substrate is formed with at least a pit corresponding to a read only area (31) and a groove corresponding to a recording/reproducing area (32) without overlapping with each other. A reflectivity of the recording layer is specified to be more than 10 %. The recording layer and the resin layer are continuously adhered over both the read only and recording/reproducing areas (31 and 32). The information recording medium is characterized in that both push-pull signal outputs T1 and T2, which are reproduced from the read only area (31) and the recording/reproducing area (32) respectively, are more than 0.1 and satisfy an inequality 1.5 ≧ T1/T2 ≧ 0.5.
