A method of producing a magnetic recording medium is provided, in which a lubricating layer is formed on a stack including a magnetic recording layer and a protective layer disposed on a substrate in this order. The method includes: coating the stack with first and second lubricants; burnishing a surface of the coated stack with an abrasive material; and removing the second lubricant present on the stack. The first lubricant has a mean molecular weight greater than that of the second lubricant, and molecules of the first lubricant are more polar than molecules of the second lubricant. The burnishing includes pressing a tape including the abrasive material against the surface of the stack to rub the surface of the stack. The removing of the second lubricant includes irradiating the coated stack with ultraviolet rays, or performing a heat treatment on the coated stack.
A method of producing a magnetic recording medium in which a lubricating layer is formed on a stack including a magnetic recording layer and a protective layer disposed on a substrate in an order as mentioned, the method comprising:
