Title: Dropout correction unit
Inventor: MIZUKAMI MINEO
IPC: H04N9/882
Filed: 1979-08-13
Abstract: PURPOSE:To make excellent corrections by improving the correlation of information by using a signal one line before and further by substituting and correcting a dropout by a signal in phase with a color subcarrier. CONSTITUTION:Input video signal 41 is outputted 45 by way of switch SW1, one- line delay circuit 43 and delay circuit 44 that delays a signal by a half cycle of a color subcarrier. Therefore, output 45 lags input 41 by one line. Output 45 is supplied to delay circuit 46 for delay of the half cycle of the color subcarrier as well. Since output signals of circuits 43 and 46 have color subcarriers in phase, adding both the signals together by adding circuit 47 puts a luminance signal in phase with output 45 to obtain signal 48 with the color subcarrier inverted in phase. Signal 48 is fed back to switch SW1 and while a dropout resides, this signal 48 is outputted by dropout detection signal 42, thereby correcting the dropout.

Filed: 1978-08-25
Abstract: PURPOSE:To record, reproduce and monitor signal by using a single light source by making a light beam thick by changing a photo image in reproducing signals, by focusing light from a light source, whose light emitting surface is rectangular, through a cylindrical lens. CONSTITUTION:Since the light emitting surface of semiconductor laser 10 is rectangular, cylindrical lenses 12 and 13 are interposed and in reproducing, cylindrical lens 13 is shifted in a light-axial direction in order to change the shape of the beam nearly in a square. To record a recording signal on the disc, the optical change of a recording material is caused by the beam waist of light made thin in a shape close to a square. To regenerate the recorded signal, irradiation with light of wider diameter than the width of an information track is needed. For the purpose, cylindrical lens 13 is shifted light-axially to obtain a light image expanded only in a direction perpendicular to the information track, thereby regenerating and monitoring the signal.
