Filed: 1988-04-08
Abstract: PURPOSE:To attain high speed recording and reproducing by equipping an optical system for recording and an optical system for reproducing in an optical card, for which plural recording units to be composed of linear track strings are recorded in a matrix shape. CONSTITUTION:To an optical card 1, a digital signal is recorded as the track string and the plural recording units (blocks) of the track strings in a prescribed number are recorded in the matrix shape. The optical system for recording and the optical system for reproducing are equipped and a laser beam from a light source 6 of the optical system for recording is deflected by a galvano-mirror 8 and scanned in the direction of the track string. Then, the digital signal is recorded. One block is formed with the prescribed track string. A reproducing light from a light source 14 for reproducing covers the range of one block and the light is image-formed to an area image sensor 19. A signal from the image sensor is converted to be digital and written to a memory and the reproducing data of the respective track strings are read from the memory. Then, the reproducing can be executed just after the recording and a check can be easily executed. Then, the high speed recording and high speed reproducing can be executed.

Abstract: PURPOSE:To secure a correct control for the gain of the intermediate frequency amplifier in case the overinput is applied to the detection circuit by installing the circuit to detect the inversion of the video detection circuit and then altering the operation of the AGC circuit by the detected output. CONSTITUTION:In case output 5 of the video detection circuit is lower than reference potential 20 of inversion detection circuit 24, the normal AGC action is given in both cases the potential of output 5 is higher and lower than AGC reference potential 11. While in case output 5 is higher than potential 20, transistor Tr8 is turned on with Tr10 turned off each. Thus a high potential is secured for base 13b of Tr13. At the same time, Tr17 and 19 are turned on and off respectively in circuit 24, and the base potential of Tr22 of inverse output control circuit 25 is heightened with the potential of base 13b lowered down. And the current between the collector and the emitter of Tr15 is increased, and the potential of the AGC output is heightened. When output 5 becomes higher than the fixed potential by the heightened potential, the gain is controlled correctly for the intermediate frequency amplifier.
