Title: Method and device for producing magnetic recording medium
Inventor: TAKAHASHI KIYOSHI
IPC: G11B5/84
Filed: 1988-11-07
Abstract: PURPOSE:To prevent an attachment at the time of forming a protective layer from being transferred to the back coating surface and from adhering to a head and to reduce an output fluctuation and loading of the head by forming a metallic thin film of a magnetic recording medium, and thereafter, forming a lubricant layer immediately after forming a protective layer on a ferromagnetic metallic thin film. CONSTITUTION:Immediately after forming a protective layer 4 on a magnetic recording medium by a plasma CVD method, a lubricant layer 5 is formed by vacuum deposition. Accordingly, before the magnetic recording medium is wound, the protective layer 4 is covered with the lubricant layer 5, and molecules of the protective layer 4 are wrapped up in the lubricant and hold a stable state. In such a way, an attachment generated at the time of forming the protective layer is scarcely transferred to the back coating surface 3 at the time of winding, and it does not adhere to a head either, therefore, an output variation and loading of the head are prevented.

Thus, a defective image where the image of the rear end part of the image formed on the recording material is made thin is prevented. Also, the recording material is prevented from being soiled at a next image forming time because the toner image is slightly stuck on a secondary transfer roller on the side of the recording material.
