The magnetic head assembly can read from and write to a plurality of tracks on a magnetic medium. The medium and assembly are relatively movable in a longitudinal direction. The assembly includes a plurality of pairs of reading poles. The assembly also includes a plurality of pairs of read loops, each adjacent and magnetically coupled to an associated pair of said reading poles. Also provided is a plurality of writing poles. Each pair of said writing poles is aligned with a different corresponding one of said writing poles. The assembly also includes a plurality of pairs of write loops, each pair of write loops being adjacent and magnetically coupled to an affiliated one of said writing poles. Each pair of write loops is selectively driveable with a pair of currents in either the same or opposite sense.
