Title: Tracking servo circuit for optical recording and reproducing device
Inventor: EGUCHI NAOYA
IPC: G11B7/085
Filed: 1986-12-08
Abstract: PURPOSE:To shorten the time required for leading from the detracking state for eccentricity or traverse to the tracking servo state by controlling a servo loop to open or close it in accordance with the detected polarity of tracking. CONSTITUTION:The photodetector on which light receiving faces A and B divided at least into two in the radial direction of a received light spot are formed is used as a photodetector 11, which receives the reflected light from a wobbling pit, to detect the fair field image of the wobbling pit. The position of this image is converted to an electric signal by the divided photodetector 11 to detect the polarity of a tracking error signal et, namely, the direction of relative movement of the projected light spot and an optical disk. Opening and closing of a tracking servo 50 are controlled by this detection signal to shorten the settling time required for locking in the tracking state after access, and leading into the tracking servo state is facilitated. Even if the extent of eccentricity of an optical disk D is large, the stable tracking state is held by a narrow-band servo loop circuit.

Abstract: PURPOSE:To reproduce sound signals always at the speed similar to the speed at the time of recording and to enable a user to listen to sounds. CONSTITUTION:The sound signals are reproduced at a speed of three times the speed at the time of recording when the video tape recorder 10 is set at a mode 1. These signals are written into a memory 34 by the address taking-in signal and writing control signal outputted from a control pulse generating circuit section 32 and the writing address signal outputted from a writing address generating circuit section 36. Reading out address signals are inputted from a reading out address generating circuit section 40 into the memory 34 every time the writing address signals are inputted therein three times. The sound signals are read out of the memory 34 by these signals and the address taking-in signal. The reading out address generating circuit section 40 is reset when a count value is made 'OFOF' and, therefore, only 1/3 the written sound signals are read out from the memory 34. As a result, the sound signals are reproduced at the speed similar to the speed at the time of recording.
