    摘要: A magnetic detection apparatus includes a first comparison circuit that waveform-shapes the amplitude of a detection signal from magneto-electric transducers by DC coupling, a third comparison circuit that waveform-shapes the detection signal by AC coupling, an oscillation circuit having a natural frequency, a control circuit that counts the output of the first comparison circuit by using the oscillation means, and a selection circuit that selects the output of the first comparison means and the output of the second comparison means. The control circuit counts rising from the next rising or falling from the next falling of an output rectangular wave of the first comparison circuit, and provides output to the selection circuit at the time point at which the count value reaches a desired value. The selection circuit selects and outputs the output rectangular wave of the first comparison circuit or the third comparison circuit.

    摘要: A magnetic detection device includes a signal processing circuit that detects a moving position and a moving direction of a magnetic mobile object using an output of a comparing circuit configured to output a signal by comparing an output signal of a magneto-electric transducer element with a threshold. A duration during which an output of the signal processing circuit is in a high level or in a low level is fixed to a period t1 or a period t2 depending on the moving direction of the magnetic mobile object. When switching of the moving direction of the magnetic mobile object takes place within the period t1 or the period t2, the signal processing circuit outputs a position signal same as a position signal indicating a position immediately before the switching of the moving direction of the magnetic mobile object due to hysteresis of the threshold of the comparing circuit.

    摘要: 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.
