Magnetic recording disk, and method and system for manufacturing a magnetic recording disk

Abstract

This invention presents a magnetic recording disk comprising a disk-shaped substrate and a magnetic film provided on the substrate for magnetic recording. The substrate is made of glass. A texture for giving magnetic anisotropy with the magnetic film is formed on a surface of the substrate. A substrate coat is deposited over the texture. The magnetic film is provided on the substrate coat. This invention also presents a method and a system for manufacturing the magnetic recording disk. The method comprises a step to form the texture with a surface of the substrate, a step to deposit the substrate coat over the texture, and a step to deposit the magnetic film on the substrate coat. The system comprises a texture formation apparatus that forms the texture with a surface of the substrate, a substrate-coat deposition apparatus that deposits the substrate coat over the texture, and a main film-deposition apparatus that deposits films including the magnetic film on the substrate coat.
