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.

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 lubricant layer is formed by vapor-phase lubrication without exposing the stacked body to atmosphere after forming the protection layer on the stacked body. A region having a gas pressure P3 is provided in a transport path of the stacked body after the formation of the protection layer and before the formation of the lubricant layer, satisfying relationships P3>P1 and P3>P2, where P1 denotes a process gas pressure at a time of forming the protection layer, and P2 denotes a process gas pressure at a time of forming the lubricant layer.

Abstract translation: 制造磁记录介质的方法在层叠体上依次形成磁记录层，保护层和润滑层。 在通过沉积设备在堆叠体上形成保护层之后，将堆叠体封闭在转移容器单元中，而不将堆叠体暴露在大气中，并且转移容器单元被输送到气相润滑沉积设备。 为了在气相润滑成膜装置内的层叠体上形成润滑剂层，将层叠体从转印容器单元取出，不会使层叠体暴露在大气中。
