Abstract

TO MANIFEST THE EXCELLENT RECORDING PROPERTY SUITABLE FOR HIGH-DENSITY RECORD AND HAVING HIGH MAGNETIC ANISOTROPY. THE MAGNETIC RECORDING MEDIUM OF THE PRESENT INVENTION INCLUDES AN ORIENTATION ADJUSTING LAYER (2), A NONMAGNETIC UNDER LAYER (3), A NONMAGNETIC INTERMEDIATE LAYER (4), A MAGNETIC LAYER (5) AND A PROTECTIVE LAYER (6) SEQUENTIALLY STACKED ON A NONMAGNETIC SUBSTRATE (1) PROVIDED ON A FIRST SURFACE THEREOF WITH A TEXTURE STREAK AND USED FOR A MAGNETIC DISC. THE NONMAGNETIC UNDER LAYER CONTAINS AT LEAST A LAYER FORMED OF A CR-MN-BASED ALLOY AND POSSESSES MAGNETIC ANISOTROPY HAVING AN AXIS OF EASY MAGNETIZATION IN A CIRCUMFERENTIAL DIRECTION THEREOF.
