In conjunction with a so-called patterned medium including recording tracks each having an array of unit minute recording portions of a magnetic material separated by non-recording portions of a nonmagnetic material, a magnetic head slider is prevented from sticking to the medium. The magnetic recording medium includes recording tracks each having an array of unit minute recording portions of a magnetic material separated by non-recording portions of a nonmagnetic material. The surface height of the unit minute recording portions is set higher than the surface height of the non-recording portions.
