A recording and/or reproducing apparatus employs azimuth-pair-head in a rotary head drum. The rotary head drum is axially shifted by a head shifting means. First tracks are formed on a magnetic tape during forward driving of the magnetic tape across the rotary head drum. On the other hand. second tracks are formed adjacent to the first tracks during reverse driving across the rotary head drum. Since the first and second tracks are formed by means of the azimuth-pair-head, azimuth gaps thereof will have different or symmetrical obliquity to each other. This successfully avoids cross-talk between adjacent tracks to allow formation of the first and second tracks in a tightly arranged fashion. As a consequence. high-density longitudinal recording without cross-talk between adjacent tracks becomes possible. |
