Title: Production of magnetic recording medium
Inventor: KAWAWAKE YASUHIRO
IPC: G11B5/85
Filed: 1988-11-17
Abstract: PURPOSE:To form ruggednesses on the surface of a magnetic layer and to improve the durability of a magnetic recording medium at the time of forming a thin film on the thin-film magnetic layer by specifying the incident angle of an atom to be vapor-deposited on a substrate to the normal. CONSTITUTION:A thin-film magnetic layer 2 is formed on a substrate 1, and a second thin film 3 is formed on the magnetic layer 2. In this case, the incident angle of an atom to be vapor-deposited to the normal is controlled to 20-90 deg.. The surface of the magnetic layer 2, on which the second thin film 3 is formed, is then etched. Namely, since the incident angle of an atom to be vapor- deposited to the normal is controlled to 20-90 deg. when the thin film is formed, the separated island thin films of the initial structure are not stuck to one another by the self shadowing effect and are grown while separated. As a result, controlled ruggednesses are formed on the surface of a medium, and the durability of the medium is improved.
