Abstract

PURPOSE:To improve corrosion resistant property, by forming a corrosion resistant non-magnetic metallic layer on a metallic magnetic recording layer. CONSTITUTION:On a tape base material consisting of a plastic film, etc., a coating film which has applied a thin film of a magnetic metal such as a Co-Ni alloy, a Cu-Ni-Fe alloy, an Fe-Co-Cr alloy, etc., or magnetic metal powder such as Fe powder, etc., together with a binder is formed as a metallic magnetic recording layer, and subsequently, on said layer, a non-magnetic corrosion resistance metallic layer consisting of a simple substance or an alloy of Cr, Pt, Au, Ru, Rh, Pd, Ir, etc. is formed to 0.02-1.0mum in thickness by means of vacuum vapor-deposition, spattering, CVD, etc.
