摘要： An optical pick-up device comprising at least one micromirror array lens. The micromirror array lens enables focusing, tracking, and/or tilt compensation in the optical pick-up device without macroscopic motions. The micromirror array lens provides the device with a simple structure, which can reduce the size, weight, and cost of the recording/reproducing system. The device is also durable for vibration. Optical pick-up devices using an array of micromirror array lenses can increase the recording/reading speed without macroscopic motions. The recording/reading speed can be increased by adding more micromirror array lenses to the lens array. The present invention can also be used to record/read information on/from a multi-layered optical disc.

摘要： The invention relates to an optical record carrier recording method for forming marks and lands by irradiating a radiation beam onto a recording surface of an optical record carrier, the radiation beam for each mark to be recorded being set to at least one write power level (Pw) capable of forming a mark during a mark period (31) and for each land between the marks to at least one bottom power level (P0) incapable of forming a mark during a land period (32). The invention also relates to a recording device for carrying out such a method. When recording a wobble signal on the record carrier, in order to achieve a better wobble signal-to-noise ratio during writing, it is proposed according to the invention that the bottom power level (P0) is temporarily raised to an intermediate power level (Pi) during an intermediate period (34). Preferably, said intermediate power level (Pi) is set within a range of from 1.5 to 6, in particular from 2 to 4, times the bottom power level (P0).

摘要： A compatible optical pickup compatibly adopting a high density recording medium and at least one low density recording medium, comprises an objective lens capable (3) of forming a light spot suitable for recording and/or reproduction on a recording surface of the high density recording medium (1a) by focusing an incident light beam for the high density recording medium capable of obtaining a high NA suitable for the high density recording medium and a light spot suitable for recording and/or reproduction on a recording surface of the low density recording medium (1b,1c) by focusing an incident light beam for the low density recording medium in the form of a divergent beam, and an actuator provided to apply tilt to the objective lens (3). The light beam for the low density recording medium (1b,1c) is incident on the objective lens in the form of a divergent beam, and when the objective lens is shifted in a radial direction with respect to the low density recording medium, a tilt is applied to the objective lens corresponding to the shift. Thus, the compatible optical pickup can compatibly adopt a high density optical disk and a low density optical disc having different thicknesses. Also, a superior aberration characteristic can be obtained when the object lens is shifted in the radial direction of the optical disc without additional optical parts with respect to the low density optical disc.

摘要： There is disclosed an optical disk apparatus (50A) to which a CD (10), DVD (20), and extra high density optical disk (30) capable of recording/reproducing an information signal with a density higher than that of the CD (10) or DVD (20) are selectively attachable. The attached optical disk is irradiated with a laser beam (L1) for the CD from an optical pickup (51) for the CD/DVD. A focus error signal (FE1) is detected based on a return light from a signal surface, and the attached optical disk is judged to be the extra high density optical disk (30) when an amplitude of the focus error signal (FE1) is not more than a predetermined value. When the attached optical disk is judged to be the CD (10) or DVD (20), a tracking error signal (TE1) is detected based on the return light from the signal surface. When the amplitude of the tracking error signal (TE1) is not less than another predetermined value, the attached optical disk is judged to be the CD (10).

摘要： An assembly for controlling the position of a lens (122) in an optical data storage and retrieval drive includes a carriage that suspends a lens holder using a plurality of flexures (260,262). A lens is mounted in the lens holder such that the center of mass of the suspended lens holder lies on the optical axis of the lens, and also coincides with the center of mass of the lens. The lens holder is capable of relative motion with respect to the carriage (106) with at least one degree of freedom. The center of mass of the carriage lies within 0.1mm of the optical axis, proximate the center of mass of the lens holder. Suspensory forces acting on the lens holder are symmetric about the optical axis. A coarse magnetic drive moves the carriage in a tracking direction, and exerts forces on the carriage that are balanced and symmetric about the optical axis, so that moments about the center of mass of the carriage are effectively absent. Inertial forces acting on the carriage, and forces reactive to the magnetic drive forces are also balanced and symmetric with respect to the optical axis, and produce insubstantial moments about the center of mass of the carriage. There is a fine tracking and a focusing drive for the lens holder. Both of these drives produce balanced and symmetric forces about the optical axis, such that moments about the optical axis are absent. Inertial forces and reactive forces acting on the suspended lens holder are also symmetric about the optical axis. As a result the objective lens moves along its optical axis, and in its tracking direction without change in attitude, and its focal point can be precisely controlled with respect to the surface of a storage medium being read or written.
