A magnetic recording and reproducing system comprising (i) a magnetic head including a first magnetic pole whose saturation flux density is at least 7 kG and whose edge face is 0.15-0.5 mu m thick, and a second magnetic pole which lies on the same side as the first magnetic pole with respect to a recording medium and whose edge face is at least 10 times thicker than that of the first magnetic pole, and (ii) the perpendicular magnetic recording medium including a perpendicular magnetization layer which has a coercive force of 250-600 Oe. in a direction perpendicular to a plane thereof and which is 0.1-0.5 mu m thick.
