摘要： An optical disk device is provided with an optical pickup that includes a convergent optical system having an objective lens for converging a light beam emitted from the laser light source to form a microspot on an optical disk and an aberration correcting optical system for controlling a spherical aberration of the convergent optical system, and performs information recording or reproduction with respect to a multi-layer optical disk having at least a first recording layer and a second recording layer. In the optical disk device, an operation of changing a correction quantity of the spherical aberration from a value adequate for the first recording layer to a predetermined value is started before an operation of moving a focus position of the microspot from the first layer to the second layer is completed. This allows a focus control to be performed stably with respect to the second recording layer in a state in which the spherical aberration correction already has been carried out, thereby preventing the focus control from failing due to an unsuccessful interlayer jump.

摘要： The Abstract has been amended. A revised Abstract is attached. An optical head includes a laser light source of emitting laser, an objective lens which focuses the laser emitted from the laser light source on an optical recording medium and an optical element placed between the light source and the optical recording medium, of which the transmittance varies depending on a voltage applied. The voltage applied to the optical element is switched so that the optical element has a lower transmittance upon reproducing a signal on the optical recording medium than upon recording a signal on the optical recording medium, at times when recording a signal on the optical recording medium and when reproducing a signal on the optical recording medium.

摘要： Tilt which is inclination of a normal of optical disk relative to optical axis of optical head is corrected with a liquid crystal element. In a driver for the liquid crystal element, a periodic waveform generator generates periodic waveform and an inverting element inverts the periodic waveform. The periodic waveform and the inverted waveform are connected to two ends of a potential divider which provides partial voltages. The periodic waveform is connected to a common electrode of the liquid crystal element, and the partial voltages of the potential divider are connected to electrodes opposing the common electrode. A structure of a driver circuit for each direction is simple. Tilt in a plurality of directions can be performed independently of each other. Spherical aberration is also corrected. When the liquid crystal element is mounted to a fixed component, deterioration due to jitters is reduced.

摘要： Laser beams respectively emitted from a SHG blue laser unit and a red semiconductor laser unit that have photo detectors respectively are turned into parallel lights by a collimator lens and then coupled by a dielectric multi-layer film mirror so as to be propagated on the same optical axis. The dielectric multi-layer film mirror is configured so as to transmit light with a wavelength of 500 nm or shorter and reflect light with a wavelength of 500 nm or longer for both P wave and S wave. The lights that are transmitted and reflected by the dielectric multi-layer film mirror pass through a polarizing hologram and a phase variable wave plate and are focused on an optical disk by an objective lens. In this manner, a simple configuration can realize a compatibility with many types of optical disks and a stable signal detection even when using a polarizing optical detection system.

摘要： An optical head apparatus consists of a semiconductor laser for radiating a light beam, a first collimator lens for collimating the light beam, a wedge-like prism for reshaping the light beam, a beam splitter for transmitting the light beam in an outgoing path and splitting the light beam in an incoming path, an objective lens for converging the light beam at an information medium in which information is stored, a plane type of hologram lens integrally formed with the objective lens for excessively correcting chromatic aberration of the objective lens to cancel out chromatic aberration of the collimator lens, a second collimator lens for converging the light beam split, a photo detector for detecting intensity of the light beam converged to obtain an information signal and servo signals, and an actuating unit for slightly moving the objective lens and the hologram lens according to the servo signals. A wavelength of the light beam is lengthened as intensity of the light beam is increased. Even though an astigmatic difference occurs in the semiconductor laser, the change of a focal length of the collimator lens cancels out the change of the astigmatic difference to prevent the occurrence of astigmatic aberration.
