Patent ID: 7258935

Claim:
A magnetic recording medium comprising: an elongated nonmagnetic support; and a single-layered magnetic layer having an orthorhombic structure formed on a main surface of said nonmagnetic support by a vacuum thin film deposition technique, wherein, said single-layered magnetic layer has a thickness from 40 nm to 100 nm, an Hcmax/Hx 0 ratio of said magnetic layer is not greater than 1.2, where Hcmax is a maximum value of a coercive force of said magnetic layer which acts in a plane perpendicular to said magnetic layer and containing a longitudinal direction of said magnetic recording medium, and Hc 0 is a coercive force of said magnetic layer which acts in the longitudinal direction of the magnetic recording medium, and said magnetic recording medium is specially adapted for recording and reproduction using a magnetoresistive magnetic transducing head or a giant magnetoresistive magnetic transducing head.
