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： 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).
摘要翻译：关于记录功率灵敏度的变化率的信息，其根据是否记录或未记录另一个记录层而变化，被预先记录在盘控制信息区域（DI）上。此外，基于该记录功率敏感度变化信息，执行记录功率补偿。相应的记录功率补偿方法分为三种类型：（1）通过判断另一层的记录/未记录状态来执行记录的类型，（2）类型，而不是判断记录/未记录的状态使用对于记录/未记录状态的最佳功率的中间功率来执行记录，以及（3）（1）和（2）的组合。

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.

摘要： In an optical recording medium having two information recording layers, a highly reliable recording can be conducted in one of the recording layers in the back regardless of the recording state of the other recording layer closer to the side of the disc on which light is incident. A first photodetector 115 detects reflected light from a recording layer 103 in the back when the light is focused thereon. A second photodetector 116 is disposed outside the periphery of the first photodetector 115 and detects reflected light from a recording layer 105 located in front. When recording in the recording layer in the back, the write power is controlled in accordance with the output level of the second photodetector.
