A recording playback apparatus has a rotary cylinder in which at least one pair of magnetic heads, one head having a different azimuth from the other, are mounted, a tape-speed control circuit that controls the traveling speed of the magnetic tape wrapped around the rotary cylinder, a magnetic-head selection circuit that selects magnetic heads so that adjacent helical tracks have different azimuths during recording, and a recording circuit that records on the magnetic tape once every n scans of the magnetic heads, where n is an integer such that n >/= 2, upon recording digital information input at a bit rate equal to (1/m) of a standard bit rate where m is a number equal to or larger than 2. <IMAGE> |
