摘要：
According to at least one embodiment, a release layer, a first mask layer containing a first metal material, an antidiffusion layer containing an oxide or nitride of the first metal material, and a second mask layer containing a second metal material are formed on a magnetic recording layer, a resist layer is formed on the second mask layer, and projections pattern is formed in the resist layer and sequentially transferred to the second mask layer, antidiffusion layer, first mask layer, release layer, and magnetic recording layer. After that, the release layer is removed.
