Abstract
PURPOSE: To obtain a high-quality reproduction picture for the normal, still and slow-motion states each by carrying out the record and reproduction with continuous N-units of the composite TV signal of one vertical scanning period which is obtained by piling the TV signals of continuous N-units in the vertical scanning period.
CONSTITUTION: The laser beam given from laser beam source 1 is given to optical modulator 3 via reflected light 2 and then undergoes the inensity modulation by the record signal through optical modulator 4 to form the light spot of a microdiameter on original disk Da via optical systems 5∼7. Here, the N-unit TV signals of the vertical scanning period in each recording track formed with every turn of disk Da are formed through continuation of N-unit composite TV signals in one vertical scanning period obtained by piling the N-unit TV signals in the vertical period which are made to be the objects of each record and reproduction. Thus, the record and reproduction is carried out for the TV signal. In such way, the high- quality is ensured for the normal, still and slow-motion pictures each.
