Abstract

PURPOSE: To improve the durability of a medium surface against the sliding or casual collision of a magnetic head slider, etc., at the time of recording and reproducing by utilizing the nonmagnetic guard bands provided between the recording tracks of the medium surface.
CONSTITUTION: This recording medium is constituted by dividing magnetic films 24, which are provided on a substrate 21 and consist of at least one layer, concentrically at a prescribed width to plural films and providing the hard nonmagnetic guard bands 25, which project slightly from the surfaces of the magnetic films 24, between the respectively divided magnetic films 24a to 24f. The protection against the sliding, collision, etc., of the magnetic head slider at the time of recording and reproducing is sufficiently assured on the surface of the magnetic films 24, by which the impact resistance of the medium surface is enhanced. In addition, the durability is improved; for example, the attraction trouble of the magnetic head slider at the time of Contact Start Stop operations, etc., is prevented.
