Abstract
A recorded information reproducing apparatus, such as a video disk player, has a memory for storing video data of one field. The reproducing apparatus generates an address access detection signal when the absolute value of the difference between a generated write address and a generated read address of the memory decreases less than a predetermined value. The address access detection signal serves to change the phase difference between the synchronous signal in the read video signal and a standard synchronous signal which is synchronized with the read clock signal, thereby finely adjusting the time axis and changing the synchronization.
