Abstract

PURPOSE:To discriminate between picture information and additional information easily by recording a one-line picture signal so that a black-plus-black part is white. CONSTITUTION:Digital signals of one-line additional information and picture information are set in buffer memories 7 and 8 respectively and those two digital signals are shifted, bit by bit, with a clock signal generated by a clock generating circuit 9 to OR corresponding bits by an exclusive OR circuit 10. This OR signal drives a driver 1-1 and at a recording part, picture information 2 and additional information 3 are superposed as shown in the figure and so recorded that a black- plus-black superpositon part 3' is white. Then, all pieces of additional information are recorded in easy-to-read states only by erasing the picture information at a minimum.
