ABSTRACT:
A method of manufacturing a magnetic recording medium which includes a bonding sub-layer substantially and forms a lubricant layer having its enough width. A method of manufacturing a magnetic recording medium includes the steps of: a) laminating an underlayer, a magnetic layer for recording, and a protection layer of amorphous carbon on a substrate of the magnetic recording medium in turn, and b) repeating a progress to said protection layer of amorphous carbon comprising an application process of applying a lubricant, a subsequent ultraviolet rays treatment process, and a subsequent washing process for removing the lubricant which is not connected to the protection layer of amorphous carbon plural times.
