ABSTRACT:
A thin film magnetic recording medium has a shape imparting substance disposed on a substrate, and a thin-film layer including at least a magnetic layer formed on the shape imparting substance. The area of each of the projecting portions of the thin-film layer which are formed by virtue of the shape imparting substance is set such as to be more than four times as large as the area of each of the particles of the shape imparting substance. The center line of each of the projecting portions of the thin-film layer may be made offset from the center line of the corresponding particle of the shape imparting substance. Thus, it is possible for the thin film magnetic recording medium to display excellent electromagnetic response properties and runability as well as durability even under a harsh environment.
