Title: Magnetic recording medium
Inventor: TANI HIROSHI
IPC: G11B5/738
Filed: 1990-09-03
Abstract: PURPOSE:To obtain a magnetic recording medium excellent in both wear resistance and impact resistance by providing a lubricant film to have larger film thickness than that of a protective film. CONSTITUTION:The lubricant film is formed to have larger film thickness than that of the protective film 2. Namely, the protective film 2 is enough hard and shows excellent wear resistance especially against simple sliding, however, it is fragile against impact since the film is too thin. By providing a lubricant 1 to larger film thickness than that of the protective film, even impact power is diffused along the traveling direction of a head (circumferential direction) to cause no fracture of the magnetic film 3. Thereby, the obtd. medium satisfies wear resistance and impact resistance and has excellent reliability.

IPC: G03G15/043
Filed: 1990-08-31
Abstract: PURPOSE:To execute stable shading correction by making a light transmitting body for deviating image forming position advance into an optical path when data for shading correcting are prepared. CONSTITUTION:A transparent glass plate 12 is under an optical path S and is located at the first position approximately parallel to the optical path S. When a solenoid 17 is driven and an actuating part leaves/enters, a bell crank rotates in the direction of an arrow A, a rotational shaft rotates in the direction of an arrow B and the transparent glass plate 12 is oscillated and stands up with the rotational shaft as a center and comes to the second position orthogonal to the optical path S. Accordingly, since reflected light from an original pressing roller 4 passes through the transparent glass plate 12, an image forming position by a converging lens 9 is deviated from the light receiving face of a photoelectric conversion element 10. Thus, the effect of the stain of the original pressing roller 4 does not appear in data for shading correction and the stable shading correction can be executed.

Abstract: PURPOSE:To make a device compact by forming magnetic tracks, of which magnetic strength is changed on a sine-curve in relation with a magnetic resistance element having the strong magnetism with the rotation of a magnetic drum, and forming at least two magnetic tracks so that magnetic strength thereof is reverse to each other. CONSTITUTION:A signal generator 3 for generating the sine-curved wave signal synchronous with the rotation of a shaft 2 of a magnetic drum 1 is fitted to the shaft 2. The signal output from this generator 3 is amplified by an amplifier 4, and is magnetized as magnetic tracks 6 (6A - 6D) by magnetic heads 5 (5A - 5D). The strength of the magnetic field of the tracks 6 is synchronized with the sine-curve wave signal from the generator 3. A MR element 7 is located in the magnetized drum 6 in contactless to the tracks 6 with a certain gap (g). Magnetic resistances MR - MR for sensing the magnetic field are located, for example, so that the current is flowed transverse to the magnetic field direction of the tracks 6A, 6B. Consequently, resistance of the element 7, which is in the relation reverse to the relation of MR and MR, and MR and MR, is increased on a sine-curve and the output voltage, which is 1/2 of the voltage, can be take out.
