Abstract

PURPOSE:To increase the travelling durability and eliminate the creaking of a tape or the attaching of a head, by mixing a specific surfactant into a magnetic paint film. CONSTITUTION:A magnetic paint film is formed by mixing a >=30pts.wt. mono or diester type surfactant of the cane sugar fatty acid. This magnetic paint film is provided on a vase film to form a magnetic recording medium.
