Abstract: PURPOSE:To display visual information by recording subsignals relating to audio signals on a magnetic tape in the running-directional center by using a short- width recording head. CONSTITUTION:Subsignals (a) and (b) relating to audio signals recorded on the main signal tracks 2a and 2b of a magnetic tape 1 are recorded on a subsignal track 3 in the center of the tape in running directions A and B through a subordinate head device 60. This device 60 has a subordinate reproducing head 7 on the up side in the running direction A of the tape 1 and a subordinate recording head 6 on the down side. The heads 7 and 6 each have two head core 61 and 62 opposite to each other with gap parts 63 and 64 between; and the head 7 is made wider than the head 6, and the part except them is provided with a magnetic shield member 65. In the running directions A and B of the tape 1, the subsignals (b) and (a) digitized and made into blocks are reproduced by the head 7 respectively and visual information is displayed by using a liquid-crystal display device, etc.
