Abstract: A method for magnetically recording/reproducing comprising recording an information signal by forming a pattern of a soft magnetic material in a magnetic recording medium; providing a magnetoeletric converting element a place neighboring a face of forming the pattern of the magnetic recording medium on which the pattern formed; applying a magnetic field to the pattern; and reproducing the information by detecting a variation of the magnetic field caused by the pattern of the soft magnetic material of the magnetic recording medium while relatively moving the magnetoelectric converting element and the magnetic recording medium.

Abstract: A magneto-optical recording medium wherein an initializing layer is covered with a resin layer for dissipating heat from the initializing layer thereby to prevent signal degradation at high recording power and thus excellent in record/reproduce repetition times, and the initializing layer is compositionally modulated thereby to broaden allowable ranges for the recording/reproducing light intensity and for the external magnetic field, besides the composition of a first or a second magnetic layer is controlled thereby to enhance recording sensitivity, and the exchange-coupling force between the first and second magnetic layers or the magnetic field strengthe to reverse the magnetization of the first magnetic layer is controlled thereby to enhance the recording/reproducing characteristics.

Abstract: In order to reduce a space required to install a facsimile apparatus and to facilitate the change of recording sheet, a recording sheet discharge tray forms a part of a body of the apparatus so that outward projection of the discharge tray from the apparatus body is prevented. Since a document cover serves as a tray for receiving discharged document and a document sheet supply tray is disposed on it, the projection of the document sheet supply tray from the apparatus body can be prevented. Since the recording sheet cassette can be drawn out from a front side of the apparatus body, the operation of supplying or adding the cut sheets can be performed from the front side of the apparatus body, and therefore a user need not move to the side portion of the apparatus body. Since one line sensor of an image reading portion can read both a document placed on an image reading surface and a document from the document sheet supply tray, the structure of the apparatus can be simplified.

Abstract: A magnetic thin film memory is provided including a plurality of magnetic thin film memory elements each adapted to record information on the basis of the direction of magnetization of a magnetic thin film thereof, the magnetic thin film memory elements being each composed of at least the magnetic thin film and a switching element. With such a constitution the magnetic thin film memory can be reduced in size while a sufficiently large signal can be obtained with a substantially improved SN ratio. A method for recording and reproduction information using the magnetic thin film memory is also provided. In another aspect, the present invention provides a magnetic thin film memory element including at least two kinds of magnetic layer, and a nonmagnetic layer which is interposed between the magnetic layers wherein the two kinds of magnetic layers are stacked so as to be coupled to each other by an exchange interaction through the nonmagnetic layer.

Abstract: A MR element which has a basically three-layered structure wherein the first and the second magnetic layer sandwich the nonmagnetic layer or of a basically five-layered structure wherein nonmagnetic layers are sandwiched between the first and second magnetic layers and between the second and third magnetic layers, respectively. The MR element of such arrangement offers a surprisingly large MR ratio under application of a sufficiently low magnetic field despite such a simple arrangement thereof.

Abstract: A magnetic thin film memory wherein the memory is composed of magnetic thin films with a layer of a higher coercive force and a layer of a lower coercive force via a nonmagnetic layer laminated repetitively, or magnetic thin films having the easy magnetization axis which lies between the perpendicular and the horizontal directions of the magnetic thin film, and information is recorded on the layer of a lower coercive force, or information is recorded by changing the direction of the magnetization by means of a magnetic field applied by two recording lines which cross the magnetic thin film, thereby to obtain a sufficient amplitude of reproduction signal even when the size of the memory is reduced.

Abstract: An information storage system for recording and reproducing information by use of irradiating light on a medium capable of overwriting information is provided. The information storage system is capable of recording information even if the light intensity is varied so as to enhance reliability. The intensity of the light at the time of overwriting is modulated, the more intense light intensity being P.sub.H and the less intense light intensity being P.sub.L. The system includes a mechanism to keep relationship of P.sub.H +.alpha.P.sub.L equal to a constant (.alpha. being a constant depending on the recording conditions). The laser drive circuit is so adjusted that P.sub.H and P.sub.L always provide an optimal condition even if P.sub.H and/or P.sub.L vary. Thus recording can always be performed under optimal conditions to enhance the reliability of the information storage system to expand the power margin of a recording medium and to increase the percentage yield of information medium.
