摘要： A first optical memory disc and a second optical memory disc are fixed to each other by an adhesive layer so as to form a dual-surface optical memory disc. In a manufacturing step, an adhesive, preferably pre-cured photo-polymer mixed with spherical spacer elements, is painted on either one of or both of the first and second optical memory discs. When a predetermined pressure is applied between the two optical memory discs, the thickness of the adhesive layer is fixed by the diameter of the spherical spacer elements. While the pressure is applied between the two optical memory discs, ultraviolet rays are applied to the adhesive layer through one of the first or second optical memory discs so as to cure the photo-polymer, thereby tightly joining the first and second optical memory discs to each other.

摘要： An optical memory element includes stripe-shaped grooves formed directly on a glass substrate. To manufacture the optical memory element, a resist film is disposed on the glass substrate, and a groove pattern is formed in the resist film. A reactive ion etching is conducted through the groove pattern formed in the resist film so as to form the guide grooves in the glass substrate. After removing the resist film from the glass substrate, a magneto-optical recording layer is formed on the glass substrate.

摘要： In an optical disk, since a header section has only one recording section for address information, the capacity of memory where a user can freely record data is increased. In an optical disk drive, four laser beams have a fixed positional relation. Based on the address information of a header section read out by at least one of the laser beams and the positional relation among the laser beams, the address information of tracks being scanned by the other laser beams is obtained. It is therefore possible to accurately record or reproduce information on the optical disk.

摘要： A magneto-optical recording medium is consisted of a recording layer, a readout layer and a writing layer. The readout layer is made of rare earth-transition metal alloys wherein an easy magnetization axis is parallel to the recording layer at room temperature, and the easy magnetization axis is perpendicular to the recording layer as the temperature of the readout layer is raised above a predetermined temperature by irradiating thereon with a light beam. The writing layer is made of rare earth-transition metal alloys having such coercive force that a magnetization direction thereof is switched by an external magnetic field at room temperature and Curie temperature that is above Curie temperature of the recording layer. With the above arrangement, an overwriting function can be achieved by adjusting a light intensity of the light beam so that the temperature falls within the range between the Curie temperature of the writing layer and the Curie temperature of the recording layer, or above the Curie temperature of the writing layer.
摘要翻译：磁光记录介质由记录层，读出层和书写层构成。读出层由稀土 - 过渡金属合金制成，其中容易的磁化轴在室温下平行于记录层，随着读出层的温度升高到预定的温度，易磁化轴垂直于记录层通过用光束照射其上的温度。书写层由具有这样的矫顽力的稀土 - 过渡金属合金制成，其磁化方向由室温下的外部磁场和高于记录层的居里温度的居里温度切换。通过上述配置，可以通过调节光束的光强度使得温度落在书写层的居里温度和记录层的居里温度之间或居里温度以上的范围内来实现重写功能的写作层。

摘要： The invention features an apparatus and method for reproducing recorded bits from a magneto-optical recording medium. The medium includes a base, a readout layer formed on the base, a transfer layer formed on the readout layer and a recording layer formed on the transfer layer. The readout and recording layers each exhibit perpendicular magnetization in a temperature range between room temperature and, respectively, the readout layer's Curie temperature and the recording layer's Curie temperature. The transfer layer is predominant in-plane magnetization at room temperature and an in-plane to perpendicular magnetization transition occurs at a temperature above room temperature. Also, the recording layer Curie temperature is lower than the Curie temperature of the transfer layer. The reproducing method includes the steps of projecting a light beam, applying a subsidiary magnetic field and reproducing information based on reflected light from the readout layer while applying the subsidiary magnetic field. The light beam is projected onto the readout layer from the side of the base so the in-plane to perpendicular magnetization transition occurs in a portion of the transfer layer, the portion corresponding to a central portion of the light beam spot. The intensity of the subsidiary magnetic field is higher than the coercive force of the readout layer and less than the exchange coupling force exerted from the recording-layer and the transfer layer to the readout layer.
