MAGNETIC RECORDING MEDIUM

摘要

PURPOSE:To provide a magnetic recording medium having a long and stable still reproduction life at a low temp. by forming a thin layer contg. a specific org. compd. on a thin ferromagnetic metallic film contg. oxygen. CONSTITUTION:The thin layer contg. the org. compd. having respectively one fluoroalkyl group of >=3C, aliphat. alkyl group of >=8C and mercapto group at the molecular terminal is formed on the thin ferromagnetic metallic film contg. oxygen. The still reproduction life at the low temp. is improved by the synergistic effect of the stable lubricating effect possessed by the fluoroalkyl group and aliphat. alkyl group and the strong reactive power of the mercapto group to the oxide layer on the surface of the thin ferromagnetic metallic film.
