Abstract

PURPOSE:To detect quickly and accurately whether information exists on a track or not by using a multihead, where magnetism-resistance transducers are arranged in accordance with individual tracks, to detect information. CONSTITUTION:When the video signal inputted from a terminal 6 is recorded on a track of a magnetic disc 1 with a recording head, a multihead 9 is used to detect tracks where information are not recorded. The head 9 is provided with magnetism-resistance transducers 20 whose number corresponds to the number of tracks, and a constant current is flowed to transducers 20 to detect voltages between transducers 20, and the envelope of the signal recorded on each track is detected. When finding the track where the envelope of the signal is not detected, a control part 12 drives a step motor 5 to move a head 3 onto this track, and recording is performed. Thus, the trouble that the disc 1 is rotated is omitted, and accurate information is obtained because the signal output attained from transducers 20 is large.
