Abstract
A method of fabricating a magnetic recording medium sequentially forms a magnetic recording layer, a protection layer, and a lubricant layer on a stacked body. The stacked body is enclosed in a transfer container unit without exposing the stacked body to atmosphere after forming the protection layer on the stacked body by a deposition apparatus, and the transfer container unit is transported to a vapor-phase lubrication deposition apparatus. The stacked body is removed from the transfer container unit without exposing the stacked body to the atmosphere, in order to form the lubricant layer on the stacked body within the vapor-phase lubrication deposition apparatus.
