Abstract

PURPOSE:When recording in the magnetic disk, etc., the magnetization locus for the composite signal of image and voice is successively fromed by the first magnetic head, and when reproducing the image signal is reprodeced by the first magnetic head, and the voice signal is is reproduced by the first magnetic head, and the voice signal is reproduced by the second magnetic head whose air gap is smaller than the width of the magnetization locus.
