Title: Optical recording medium
Inventor: SAITOU ICHIROU
IPC: G11B7/24
Filed: 1984-05-21
Abstract: PURPOSE:To execute exact tracking with less error by forming an photomagnetic recording layer which absorbs light of a specific wavelength and an optical recording layer which allows transmission of light of a specific wavelength and absorbs light of another specific wavelength on a reflecting layer provided on a substrate. CONSTITUTION:The reflecting layer 2 is formed on the glass substrate 1a and the photomagnetic recording layer 3 is formed thereon. The optical recording layer 4 is then formed thereon. Recording is executed by irradiating laser light 5 having the specific wavelength at which said light is not absorbed by the layer 4 and is absorbed by the layer 3 and the laser light 6 having another specific wavelength at which said light is absorbed by the layer 4. A magnetic field is preliminarily impressed to the layer 3 by a magnetic head 7 and if the light 5 is irradiated thereto, a recording bit 8 is recorded as information. The recording bit 8 is recorded in the layer 4 by the light 6. A magnetic Kerr effect and magnetic Faraday effect are utilized to read the bit 8 by the laser light 5. The bit 8' is read out as a difference in reflectivity by the laser light 6. A tracking error is eliminated during this time.

Title: Mirror surface plate inspection device
Inventor: MOTOOKA TORU
IPC: G01B11/30
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To improve a working efficiency and to reduce the labor of an operator by inspecting a mirror surface plate based on an inspection signal being outputted from a camera and at the same time by controlling a driving part and adjusting the focus of the camera automatically. SOLUTION: When a material to be inspected (mirror surface plate) 9 is stopped at an inspection position, a camera 1 being mounted diagonally to a lighting device 6 picks up the image of reflection light from the mirror surface plate 9 and outputs an obtained inspection image signal to an inspection signal processing device 5. The processing device 5 extracts the width of the signal waveform of a digital signal being outputted from a conversion part 15 by an extraction part 16, and furthermore detects the signal width of a slice level being set to a part with a voltage that is slightly lower than that of the maximum input signal value of the signal waveform by a comparison part 17. A control device 24 controls a motor 20 based on the detection signal and adjusts the focus of a lens 2 of the camera 1, thus detecting the focus adjustment position of the lens 2 accurately.  Therefore, a ring 3 for adjusting the focus of a lens can be automatically adjusted, thus reducing the labor of an operator.
