Abstract:
A method of fabricating a magnetic recording medium includes forming the lubricant by depositing a first lubricant on the stacked body after forming the protection layer, by vapor-phase lubrication deposition, without exposing the stacked body to atmosphere, and depositing a second lubricant that is dissolved in an organic solvent onto the stacked body after depositing the first lubricant. A molecular mass of a compound included in the first lubricant is higher than that of the second lubricant, and a chemical polarity of the compound included in the first lubricant is lower than that of the second lubricant.
