摘要： An interference type optical head and an optical disk apparatus which have a signal amplification effect and can be manufactured in sizes comparable to conventional optical heads. In an optical disk apparatus that performs signal amplification by making a light, which is used as a reference light without being irradiated on an optical disk and, interfere with reflected light from the optical disk, a corner cube prism that reflects the reference light is mounted on the same actuator as an objective lens. A movable portion adjusts the optical path length of the interfering light in accordance with the kind of optical disk being read and the recording layer being read. A wedge prism may be used for the movable portion, and a spherical aberration correction lens and an optical path length adjusting component may be moved integrally.

摘要： An interference type optical head and an optical disk device that can easily adjust an optical path length difference of a couple of lights, ensure higher signal amplification effect, and are suitable for reduction in size are provided in order to improve a regeneration signal quality with amplification of signal in the case where reflectivity of each layer must be lowered and relative noise for the signal increases because read speed is high in a multilayer optical disk. In view of essentially improving an S/N ratio of the regeneration signal in high-speed rotation of a multilayer disk, a plurality of interference phases are generated and an optical system for differential calculation has been reduced in size with an angular selective polarization conversion element in the optical disk device for amplifying the signal with interference of the light not radiated to the disk with the reflected light from the disk. Moreover, adjustment of reflection mirror angle of the reference light is no longer required by using a corner cube prism as the reference light reflection mirror and highly accurate signal detection can also be realized with a simplified structure.

摘要： Information about a variation ratio of the recording power sensitivity, which varies depending on whether another recording layer is recorded or unrecorded, is recorded onto a disc control information area (DI) in advance. Moreover, based on this recording-power-sensitivity variation information, recording-power compensation is performed. The corresponding recording-power compensation method is classified into three types: (1) type in which the recording is performed by judging the recorded/unrecorded states of another layer, (2) type in which, instead of judging the recorded/unrecorded states of another layer, the recording is performed using an intermediate power of the optimum powers for both of the recorded/unrecorded states, and (3) combination of (1) and (2).

摘要： Provided is an optical disc apparatus including an interference-type optical disk signal detection system, which allows an optical path difference between two kinds of light to be controlled easily, which has a high signal amplification effect, and which is suitable for miniaturization of an optical system. An interference-type optical system is integrally formed to stabilize an optical path difference between signal light and reference light. At the same time, means for controlling an optical path length of the reference light is attached to a reference mirror, and thereby controls signal amplitude so as to be constantly set the maximum in response to a change in the optical path length with time due to a variation in the thickness of a cover layer of an optical disk, a temperature and the like. Moreover, the optical system is miniaturized by using a Twyman-Green type interference optical system.

摘要： The invention provides an optical disk that enables high-speed reproduction of address signals. A wobble address system for optical disk supports various types of synchronization, such as phase synchronization, bit synchronization, word synchronization, etc., to be established easily with high detection reliability with the use of an self-orthogonal code. Thus, the invention provides a method for easily synchronizing an address signal, i.e., high-speed reproduction of the address signal. Further, by virtue of an efficient modulation system of the address signal and redundancy thereof, it becomes possible to detect address information with high reliability. This capability is particularly effective in optical recording/reproduction with a blue light source whose signal light quantity and reproduction quality are prone to reduce. Moreover, other additional data of the address data is preserved in the wobbles, which provides medium information to a rewritable optical disk without using embossed pits such that a high-reliability disk (with enhanced security) is realized with a low cost and easily.
