Title: Production of magnetic recording medium
Inventor: SAKAMOTO MASANORI
IPC: C23C14/24
Filed: 1980-09-18
Abstract: PURPOSE:To obtain a magnetic recording medium suited to the vertically magnetized recording in a quick and stable way, by applying the AC voltage to a substrate when forming a recording medium layer made of a Co-Cr alloy on the substrate by an ion plating process. CONSTITUTION:The inert gas for discharge is led into a vacuum tank 1 after the tank 1 is evacuated, and then high frequency voltage is applied to a coil 5 from a high frequency power source for discharging 7 to perform glow discharge. Then the high frequency voltage is applied to an accelerating electrode 3 from a high frequency power source for accelerating 8. The particles of Co and Cr plus their alloy are evaporated from evaporating sources 2a and 2b. Thus a Co-Cr alloy thin film is formed on a substrate 4 that is supported by the electrode 3. As a result, the electrifying phenomenon which is easily caused when a substrate made of an insulated material is used can be liminated since an AC is applied to the electrode 3. Accordingly, the discharge occurring between the electrode 3 and the substrate 4 can be prevented to obtain a recording medium having reduced coarseness on its surface.
