摘要： A magnetooptical recording medium capable of performing an over-write operation by only modulating an intensity of a light beam without modulating a direction of a bias field is known. This invention provides a multilayered medium which has an advantage of a large margin for an initial field Hini. for initializing the medium, and can stably perform an over-write operation, or which can increase a beam intensity in a reproduction mode to attain a high C/N ratio.

摘要： A multi-layered magnetooptical recording medium that satisfies predetermined formulas is over write capable when used, in a recording method and apparatus, with a jointing field, i.e., a magnetic field the intensity of which decreases continuously from an initial field to a bias field having the same direction as the initial field, permitting greater freedom in the choice of media compositions. In a two-layer structure including magnetically coupled recording and reference layers, recorded data may advantageously be reproduced from the reference layer.

摘要： A method of this invention is a non-overwritable method of recording information on a magnetooptical recording medium in which at least two layers including a first layer comprising a magnetic thin film having a perpendicular magnetic anisotropy, and a second layer comprising a magnetic thin film having a perpendicular magnetic anisotropy, and having a Curie temperature higher than or almost equal to a Curie temperature of the first layer are stacked to be exchange-coupled to each other, and a direction of magnetization of only the second layer can be aligned in a predetermined direction by a first external field at a room temperature while a direction of magnetization of the first layer is left unchanged. The medium which has already been set in a state wherein the direction of magnetization of the second layer is aligned in the predetermined direction, and a interface magnetic wall is formed between the first and second layers is prepared. A beam is radiated on the prepared medium while rotating the medium. The beam is pulse-modulated according to information to be recorded between a first intensity level for giving, to the medium, a temperature lower than the Curie temperature T.sub.C1 of the first layer, and higher than or equal to a lowest temperature T.sub.LS for causing the interface magnetic wall between the first and second layers to disappear, and a second intensity level for giving, to the medium, a temperature lower than the temperature T.sub.LS. In another aspect of this invention, the first intensity level is set at a level for giving, to the medium, a temperature equal to or higher than T.sub.C1 and lower than the Curie temperature T.sub.C2 of the second layer.

摘要： A medium includes a readout layer, a memory layer, an adjusting layer for an exchange coupling force .sigma..sub.W, and a writing layer, and can perform an over-write operation upon radiation of a modulated laser beam. The readout layer essentially consists of GdFeCo, the memory layer essentially consists of TbFeCo, the adjusting layer essentially consists of GdFeCo, and the writing layer essentially consists of DyFeCo. The C/N ratio of the medium exceeds 53 dB. The C/N ratio is a value obtained when a plurality of mark.sup.H having a period of 1.6 .mu.m are written, and are read out so that medium noise is maximized as compared to other noise components.

摘要： A non-overwritable recording apparatus comprises a magnetooptical recording media including at least first and second exchange-coupled layers having perpendicular magnetic anisotrophy, the Curie temperature of the second layer being higher than that of the first layer. The direction of magnetization of the second layer is aligned in a predetermined direction, without changing the direction of magnetization of the first layer, and the direction of magnetization of the first layer is aligned in a direction such that an interface magnetic wall is formed between the first and second layers in at least each recording portion of the medium. While the medium is rotated, a laser beam is radiated on the medium and is pulse-modulated, according to information to be recorded, between a first intensity level which imparts to a recording portion a temperature at least as high as the Curie temperature of the first layer and lower than that of the second layer and which thereby forms a mark having no interface magnetic wall between said first and second layers, and a second intensity level, including zero-level, which imparts to a recording portion a temperature lower than a lowest temperature at which the interface magnetic wall disappears, whereby the mark is not formed. In a modification, the first intensity level imparts to a recording portion a temperature lower than the Curie temperature of the first layer and at least as high as a lowest temperature at which an interface magnetic wall between the first and second layers disappears.

摘要： An IGBT has an emitter region, a top body region that is formed below the emitter region, a floating region that is formed below the top body region, a bottom body region that is formed below the floating region, a trench, a gate insulating film that covers an inner face of the trench, and a gate electrode that is arranged inside the trench. When a distribution of a concentration of p-type impurities in the top body region and the floating region, which are located below the emitter region, is viewed along a thickness direction of a semiconductor substrate, the concentration of the p-type impurities decreases as a downward distance increases from an upper end of the top body region that is located below the emitter region, and assumes a local minimum value at a predetermined depth in the floating region.
