A magnetic recording medium capable of preventing contact with a magnetic
head for use in recording or reproduction, during recording or
reproducing of record data. The magnetic recording medium has a
disk-shaped substrate having a surface formed with an annular
data-recording area, an outer area outward of the data-recording area,
and an inner area inward of the same. The annular data-recording area has
a plurality of tracks separated from each other by concentric separating
grooves. At least one of the outer area and the inner is subjected to
lift-adjusting treatment for enabling adjustment of lifts applied to the
magnetic head. This makes it possible to effectively prevent the magnetic
head from being inclined to be brought into contact with the magnetic
recording medium.
