Summary:A PERPENDICULAR MAGNETIC RECORDING MEDIA AND METHOD OF MANUFACTURING THEREFORE INCLUDES A NONMAGNETIC SUBSTRATE (1), AN UNDERLAYER (3) DEPOSITED ON THE NONMAGNETIC SUBSTRATE, AND A MAGNETIC RECORDING LAYER (4) FORMED ON THE UNDERLAYER, QUICKLY HEATED, AND QUENCHED. A PROTECTIVE LAYER (5) IS DEPOSITED ON THE MAGNETIC RECORDING LAYER, AND A LIQUID LUBRICANT LAYER (6) IS DEPOSITED ON THE PROTECTIVE LAYER, TO IMPROVE AN UNIAXIAL ANISOTROPY KU AND A COERCIVE FORCE HC OF THE MAGNETIC RECORDING LAYER.(FIG 2)
