Abstract

PURPOSE: To make erasable the recording track in advance, ahead the recording of line letter signal, by using the rotary recording sheet as the memory means of TV signal.
CONSTITUTION: The composite character signal is selected from the TV signal in which a plurality of line signals of a plurality of composite character signal of a plurality of channels are superimposed during a given period within the vertical frequency period, and the line character signals of composite line signal are sequentially picked up and memorized, obtaining the field character signal of the desired channel through sequential readout of the line character signal memorized. Further, the rotary recording sheet 1 such as rotary magnetic sheets is used as the memory means, and the recording track 2 can be erased in advance, ahead the recording of the line character signal of each composite line signal of the composite character signal in the desired channel to the rotary recording sheet 1.
