摘要： A load sharing system composed of a plurality of servers that are interconnected over a network for providing optimum and efficient operations at high reliability. The system employs a plurality of servers and a communication controller. A state manager in the communication controller first establishes connection paths on the network to reach the state management agents. The state manager then performs a centralized management of activity status of the servers based on status information collected from the state management agents via the established connection paths. A distribution processor disposed in the communication controller receives service requests from user terminals via a network and determines their respective destinations according to management data provided by the state manager. The distribution processor then forwards the service requests to the servers over the communication medium to direct their execution. An operation controller activates or deactivates a plurality of parameters which will define how to distribute the service requests to the applications.

摘要： An optical disk substrate in which a winding groove, which is winding in accordance with address information, and a normal groove, which is not winding, are placed alternately in the radial direction as tracking guides used for tracking control. With respect to this optical disk substrate, a laser beam, which is used for forming patterns for the tracking guides, is applied while being switched alternately between the first mode that exerts oscillations in the disk radial direction in accordance with the address information and the second mode that does not exert oscillations. An optical disk has a construction in which at least a recording layer is formed on the optical disk substrate.

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.

摘要： A magneto-optical disk provided with a record layer having a recording magnetic domain where data are recorded, an auxiliary reproduction layer for transferring the record data in the record layer to a reproduction layer by generating a floating magnetic field corresponding to the data in the record layer, and the reproduction layer from which the data are read out through irradiation of a light beam, which are sequentially layered while interposing nonmagnetic intermediate layers therebetween. The stable magnetic domain width in the auxiliary reproduction layer is shorter than the recording magnetic domain width at room temperature and extends as the temperature rises and becomes longer at or above a first temperature. The stable magnetic domain width in the reproduction layer is longer than the recording magnetic domain width at room temperature and lessens as the temperature rises and becomes shorter at or above a second temperature which is lower than the first temperature. The first and second temperatures satisfy a condition expressed as: room temperature
