Method of manufacturing magnetic recording medium

Abstract

A method of manufacturing a magnetic recording medium includes burnishing, with an abrasive material, a surface of a stack including a magnetic recording layer and a protective layer stacked on a substrate in order of the magnetic recording layer and the protective layer. The burnishing of the surface of the stack includes using a long abrasive tape including abrasive grains as the abrasive material fixed onto a support in a state of being wound in roll form, and pressing the abrasive tape, supplied from the state of being wound in the roll form, against the surface of the stack so as to rub the surface of the stack. The abrasive tape in the state of being wound in the roll form is subjected to vacuum treatment in advance such that loose abrasive grains are reduced.
