ABSTRACT:
A magnetic recording medium and a manufacturing method for making it are disclosed. The method facilitates preventing the lubricant deposited on the end face of the magnetic recording medium from migrating onto the major surfaces thereof. The lubricant deposited on an end face of a magnetic disk, which may migrate onto the major surfaces of the magnetic disk, is wiped off by the rotating magnetic disk with the lubricant deposited thereon, by spraying a solvent onto a wiping tape while feeding the wiping tape, and by pressing the wet wiping tape containing the solvent to the end face of the magnetic disk with a pad while the feeding of the wiping tape is discontinued. Alternatively, the lubricant deposited on the end face of a magnetic disk is solidified to deprive the lubricant of its fluidity by rotating the magnetic disk with the lubricant deposited thereon while irradiating it with ultraviolet radiation from a UV lamp through a slit opened in a shield on the lamp to the end face of the magnetic disk.
