摘要： In forming steps of a recording layer or a dielectric layer of a phase change type optical disk by sputtering, a discharge gas which includes at least one of Kr gas and Xe gas is used. Alternatively, at least one of Ar gas and N.sub.2 gas may be further added to the discharge gas. Forming the recording layer or the dielectric layer of the phase change type optical disk in these discharge gases enables preventing of the introduction of the discharge gas into each layer during the forming steps. As a result, the void generation and growth in the recording layer is suppressed. Consequently, the deterioration of the cycle life characteristics due to repeated overwrite operations can be restrained. Therefore, high reliability and long life of the phase change type optical disk is attained.

摘要： An optical disk apparatus that performs focus control and tracking control, the focus control focusing an objective lens on an optical disk, and the tracking control making the objective lens track a partial area on the optical disk. The optical disk apparatus has a light-blocking element and a light detector. The light-blocking element is disposed on a first light path on which light reflected by the optical disk travels, and blocks a part of the reflected light. The light detector detects, for the focus control, the reflected light which passes the light-blocking element. The light-blocking element has a predetermined area for blocking the reflected light, the predetermined area extending along a direction optically corresponding to the tracking direction in which the objective lens tracks, for the tracking control, the partial area on the optical disk.

摘要： In an optical pickup, an optical guide member is provided in an optical path of light from a light source, and has a plurality of inclined surfaces inclined with respect to a light beam emitted from the light source. A light-receiving element is provided for receiving light and for converting the received light into an electrical signal. The optical guide member and the light-receiving element are contained in a packaging member. The light beam from the light source is reflected by the plurality of inclined surfaces of the optical guide member, and then are directed to a recording medium. The reflected light from the recording medium is directed to the light-receiving element. At least one of dry air and inert gas such as nitrogen gas is charged in the interior of the packaging member at a pressure of 0.5 atm to 1.5 atm, thereby preventing the optical characteristics from being degraded.

摘要： An optical information storage medium includes a multilayer structure formed on a substrate. The multilayer structure is formed by a sputtering process in a discharge gas and includes at least a first dielectric layer, a recording layer which shows reversible phase change between an amorphous phase and a crystal phase, and a second dielectric layer. The multilayer structure contains sufficiently small amount of the discharge gas so that a limited amount or less of voids of the discharge gas generates in the recording layer during repeated overwrite operations.
