Abstract

PURPOSE:To improve the durability of a medium and magnetic head without impairing high-density recording characteristics even in a floppy disk on which the magnetic head travels in continuous contact therewith by providing 2 layers of protective layers respectively consisting of thin films of required materials on magnetic recording layers having perpendicular magnetic anisotropy. CONSTITUTION:The magnetic recording layers 2 which consist of thin films of a Co-Cr alloy suitable for high-density recording and have the perpendicular magnetic anisotropy are provided on both faces of a film-like nonmagnetic substrate 1 consisting of a resin material, etc. The 1st protective layers 3 which are thin films of diamond-like carbon having high hardness, the 2nd protective layers 4 which are thin films of silicon oxide having relatively low hardness and elasticity, lubricating layers 5, etc., are laminated on the layers, by which a magnetic recording medium is formed. The protective layers 4 with which the magnetic head comes into direct contact are not high in hardness according to this constitution, and therefore, initial scratches arise hardly and the durability of the medium and the magnetic head is enhanced without impairing the high-density recording characteristics.
