ABSTRACT:
In a magnetic recording device for magnetically recording Information on a magnetic recording medium by a magnetic head, the magnetic head is so oriented that the magnetic flux leaking at the head gap is at right angles with the direction of relative movement between the magnetic head and the magnetic recording medium and parallel with the surface of the magnet recording medium. The magnetic recording medium may have track portions formed of a magnetic material, and intertrack portions formed of a nonmagnetic material. The magnetic recording medium may alternatively be formed of convex track portions and concave intertrack portions.
