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： Light emitted from a laser is divided into two light waves so that the ratio of the power of one light wave to the power of the other will be appropriate. The resultant light waves are irradiated to the same track on a medium. The preceding spot is used for erasure, and modulated so that the same pattern as the one formed with a recording pulse will be formed. The high-power component of the modulated light of the erasing spot causes the temperature of a recording layer to be equal to or higher than the melting point. The medium-power component of the modulated light forms a crystallizing temperature area on the recording layer. A liquid crystal diffraction grating is used to divide power, and a power division ratio is variable and controllable.

摘要： An information recording method and information recording apparatus is capable of resolving the trade-off relation between recording density and transmittance, wherein either the reproduction (playback) signal quality or the recording sensitivity is lowered. For this purpose, a voltage is applied by way of ball bearings or slip rings to a specified layer of a medium having multiple layers. The light transmittance of the recording layer is changed by application of this voltage. The tradeoff relationship between recording density and transmittance is eliminated thereby, and the recording density and transmittance levels are both improved, so as to enhance the recording reliability.

摘要： Before original information is recorded in areas such as a recording medium management area where the same pattern of information is recorded many times, a dummy pattern that minimizes a recording film flow is recorded. Because the direction of the recording film flow depends on the length of a mark length, the dummy pattern is a pattern including marks with a unique length. Randomly or sequentially selecting and recording a plurality of dummy patterns, each with a recording film flow direction different from others, prevents jitters, which will be caused by the recording film flow, from increasing.
