Abstract

PURPOSE:To reduce a recording and demagnetizing operation, by using a magnetic recording medium having easy magnetization direction risen with a slope from the inside of a magnetic layer plane toward the moving direction of a magnetic head. CONSTITUTION:The system consists of a nonmagnetic substance base 4, magnetic substance layer 3 provided on it, and magnetic head 1 having a head gap 2. The magnetic substance layer has a value of Br which is a strength of residual magnetization measured at a rising angle by 45 deg. from the inside of magnetic substance layer toward the moving direction x of the magnetic head with relative movement in parallel with the surface of the magnetic substance layer, greater than the value of Br measured at a falling angle of 45 deg. by >=25%.
