Title: Optical disk recording and reproducing device
Inventor: MIZUNOE KATSUZO
IPC: G11B7/12
Filed: 1985-01-09
Abstract: PURPOSE:To attain a high-speed access and the highly accurate control of a control system by providing a mobile head part which can move in the radius direction of an optical disk containing a light source and a control optical system and a fixed head part containing an information reproducing part includ ing a reproduction optical system. CONSTITUTION:The outputs of PIN photodiodes 20 and 21 are amplified by a preamplifier, and a reproduction signal is obtained from the difference between both amplified outputs. The reproduction of signals is not effected at all even in case a mobile head part 1 moves in the radius direction of an optical disk 3 to produce the change of the distance from a fixed head part 2 since light beams 24 and 25 are parallel to each other. Furthermore the detection accuracy of both diodes 20 and 21 is not affected even if the shift or rotation is given to the part 1 owing to the shift of the part 1 since the reproduction signal is converted into the optical intensity singal with beams 24 and 25. At the same time, the effects of the thermal deformation, the vibration and the change with time are reduced since the optical paths of the focusing and tracking control systems are short. Thus it is possible to attain a high-speed access and the highly accurate control of the control system.

Title: Production of magnetic recording medium
Inventor: SHINOHARA KOUICHI
IPC: C23C14/54
Filed: 1982-01-08
Abstract: PURPOSE:To ensure the uniform magnetic properties over a wide area, by vapor depositing a ferromagnetic layer on a high polymer molded product substrate while moving this substrate along a rotary supporter and then taking up the substrate when the temperature of the substrate is set at a level lower than the glass transition point after cooling the supporter. CONSTITUTION:A high polymer substrate 1 of a polyethylene telephthalate film within a vacuum vapor depositing device is rewound by a shaft 3 and then moved along a rotary supporter 2 having 2m diameter and flowing a refrigerant of 5 deg.C. Then Co and Ni is vapor deposited obliquely on the substrate 1 from an evaporating source 5 via a mask 6. Thus a ferromagnetic layer is formed on the substrate 1. In this case, the supporter 2 is cooled down at 5 deg.C which is lower than the glass transition point 69 deg.C of the film substrate 1. Therefore the substrate 1 is cooled continuously down to a level lower than 69 deg.C until it is separated from a roller 7 at a point D3. As a result, a creep or a distortion due to a local deformation is not produced. Thus the output stability is improved without generation of noises for a magnetic recording medium.

IPC: G06F9/38
Filed: 1984-01-11
Abstract: PURPOSE:To attain easily the high-speed parallel processing by processing in parallel the data transfer, etc. regardless of the CPU control and according to the control information corresponding to the address given from the CPU. CONSTITUTION:A microprocessor CPU1 gives an address to a memory 2 and receives an instruction word and also transfers the control information corresponding to said instruction word to a decoder 5 and a counter 6. The decoder 5 applies a write enable signal to a data memory part 4 and also gives a device selection signal to a peripheral circuit of the CPU1 as well as to an input/ output circuit 3. While the counter 6 sends a reset signal to a check sum register 9. Then the instruction word is executed by the CPU1. The size of the data memory part 2 is decided in consideration of the data transfer speed between a peripheral interface circuit 10 and a peripheral circuit, the size of a block and the generation factor of a transfer error. Thus it is possible to perform parallel transfer of data with no intervention of the CPU1 excluding an instruction fetch just by applying an address.

IPC: G02B5/18
Filed: 1983-01-11
Abstract: PURPOSE:To eliminate a difference in sphericity and to reduce coma-aberration by regarding the concave surface side of a plano-concave lens as an incident surface where parallel light strikes, forming a Fresnel zone on the plane side, and specifying the radii of rings and the thickness, refractive index, radius of curvature, etc., of said plano-concave lens. CONSTITUTION:A Fresnel zone plate 3 uses the concave surface of the plano- concave lens 19 as the incident surface where the parallel light strikes and has the Fresnel zone 2 on the plane side; and simultaneous equations I -VI hold for radii of rings, and the refractive index, thickness, and radius of curvature of the plano-concave lens 19 are so determined that the evaluated amount of residual coma-aberration is reduced, thereby reducing the spot diameter of a diffraction limit and coma-aberration in a transparent material 8 which has a >=1 refractive index. Thus, the radii rk of rings of the Fresnel zone, thickness d1 and refractive index n1 of the concave transparent plate, and thickness d2 and refractive index n2 of the parallel transparent plate are determined, and consequently the coma- aberration of projected light is eliminated even if the incident parallel light slants to an optical axis, so that a sharp spot is obtained at a convergence point 7.
