摘要： A magneto-optical recording medium, including a recording layer, a transfer control layer magnetically coupled to the recording layer, and a reproduction layer. The recording layer includes a recording magnetic domain in which information is recorded by a magnetization direction vertical to the surface of the film. The reproduction layer includes a reproduction magnetic domain in which information in the recording layer is transferred and formed as a magnetization direction by magnetic coupling. The direction of magnetization of the recording magnetic domain of the recording layer and the direction of magnetization of the transfer control layer corresponding to the recording magnetic domain are in opposite directions in at least part of the range of temperatures less than a transfer temperature where the reproduction magnetic domain is transferred to the reproduction layer. The Curie point temperature of the transfer control layer is higher than this transfer temperature.

摘要： A magneto-optical recording medium includes a first magnetic layer and a second magnetic layer. The first magnetic layer is an in-plane magnetized film at room temperature, but changes to a perpendicular magnetized film at a predetermined temperature higher than room temperature, and is thin enough to allow a light beam to pass through it. The second magnetic layer has perpendicular magnetic anisotropy and is arranged to allow magnetic coupling to the first magnetic layer when a light beam for reproduction comes from the first magnetic layer side. The rotation of the polarization plane of a light beam which is reflected off the first magnetic layer and the rotation of the polarization plane of the light beam which passed through the first magnetic layer and reflected off the second magnetic layer compensate each other, thereby canceling each other.

摘要： It is an object of the present invention to provide a magneto-optical recording medium including a recording film having at least a reproduction layer, an intermediate layer, and a recording layer, on an optical disk substrate, wherein the recording film is a magnetic film that is magnetically coupled and that has magnetic anisotropy in a direction vertical to its film surface, the recording magnetic domains formed in the recording layer are transferred to the reproduction layer, and recording information is reproduced by domain wall movement in the reproduction layer, and the recording layer has columnar structures that are oriented substantially vertically. Thus, it is possible to provide a magneto-optical recording medium with which signals below the diffraction limit of the light spot for recording and reproducing information can be reproduced at high speed, with which the recording density and the transfer speed can be significantly increased, and with which stable recording magnetic domains can be formed even if recorded at high density.

摘要： A control apparatus controls an imaging apparatus that includes a focus detection unit configured to detect a focus state of an image forming optical system. The control apparatus includes a collectively setting unit configured to read initial setting values corresponding to a selected operation mode from a storage unit, and set setting values of a plurality of setting items to initial setting values, and a setting value changing unit configured to individually change setting values of the setting items set by the collectively setting unit and store the changed setting values in the storage unit. An operation of the focus detection unit is controlled by the operation mode in which the setting values have been changed by the setting value changing unit.

摘要： A mark detection apparatus includes a reading unit, a converter, and a determination part. The reading unit reads an image on a document. The converter compares respective portions of the image read by the reading unit with a plurality of preset reference patterns, and converts a portion of the image to a character associated with a corresponding reference pattern. The determination part determines that the portion of the image to have been compared on the document is a mark in a case in which the character converted by the converter is a preset first reference character, and that the portion of the image to have been compared on the document is not a mark in a case in which the character converted by the converter is not a preset first reference character.
