description	PURPOSE: To decrease medium noises and to enhance S/N by specifying the film thickness of nonmagnetic ground surface films to >=0.3 to =2.4 kilooersted. CONSTITUTION: Amorphous plating layers 22, 22' which consist of an Al-4wt.% alloy having an outside diameter of 95mm, a bore of 25mm and a thickness of 0.8mm and have a film thickness of 13μm are formed. The product Brxt of the total (t) of these alloy based magnetic layers and the residual magnetic flux density Br measured by impressing a magnetic field in the relative traveling direction of the magnetic head with a magnetic recording medium at the time of recording is specified to >=10 to =2.4 kilooersted, by which the recording and reproducing of the high-density information of >=2 gigabits per square inch are made possible as well.
