Abstract

PURPOSE: To prevent the corrosion of the magnetic metal (alloy) in a resin layer by forming a metal (ally) thin film having the specific resistance value on the resin layer which is provided on a non-magnetic substrate and is dispersed with fine particles of ferromagnetic metal (alloy) thereby forming the magnetic recording medium.
CONSTITUTION: A magnetic layer 2 composed of a resin layer dispersed with fine particles of ferromagnetic metal of 1μ or under in particle size such as iron is formed on a non-magnetic substrate 1 such as polyethylene terephthalate film and further a metal (alloy) thin film 3 of resistance value 10Ω/cm2 or under is formed by using a vacuum evaporation method, electroplating method or other. Metals (e.g., gold) of smaller ionization tendency than the magnetic fine particle metal used, metals (e.g., chromium) which develop corrosion preventiveness by forming possive state, etc. are used for the abovementioned metal thin film 3.
