Abstract
In manufacturing a magnetic recording disk, a magnetic film for a recording layer is deposited on a substrate of the magnetic recording disk in a magnetic-film deposition chamber, and the substrate is transferred from the magnetic-film deposition chamber to a lubricant-layer preparation chamber without exposing the substrate to the atmosphere. Then, a lubricant layer is prepared on the substrate in the lubricant-layer preparation chamber.
