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： An optical recording element comprising a recording medium which includes an information recording area formed at every unit in a non-continuous condition, the recording medium further including sample pits disposed at intervals of a fixed distance for providing basic information about the locations of recording units in the same track. Each sample pit comprises a plurality of pits disposed next to the sequence of the recording units so that the spacing between the pits differs from the spacing between the recording units. At least one of the plurality of pits is a long-sized inclined pit which is inclined at an angle in the range of 6.degree. to 80.degree. to a recording track. A driving system for driving the optical recording element for recording information in the non-continuous recording area or erasing information stored therein with a light beam the output of which is varied as required and checking whether said recording or erasing has been correctly performed, within a very short time in which the light beam passes through the non-continuous recording area. By using the optical recording element in combination with its driving system, the processing speed for reducing, erasing and verifying these functions can be greatly improved and the irradiating position of the light beam at every recording unit can be correctly controlled.

摘要： A control equipment with a built-in communication apparatus is provided which realizes a delay required for communication without a software intervention while at the same time reducing a load of the communication processing. The control equipment with a communication apparatus includes: a communication device to communicate with a plurality of destinations; and a decision device to determine a mode requiring a reception completion interrupt and a mode not requiring the reception completion interrupt. If the decision device decides that the reception completion interrupt is not necessary, the communication device transmits data to one or more destinations and also virtually transmits data to a second destination different from the first intended destination.
