Summary:PURPOSE:To improve both durability and recording-reproducing characteristics such as high-frequency characteristics. CONSTITUTION:An intermediate layer contg. at least one kind of compd. having <=0.1mum average particle diameter selected from among lanthanum oxide, samarium oxide, terbium oxide, europium oxide, yttrium oxide, lead titanate zirconate, lanthanum lead titanate zirconate, aluminum titanate and barium silicate is formed on a substrate and a magnetic layer contg. magnetic powder such as metal powder, cobalt stuck iron oxide powder or hexagonal ferromagnetic powder is formed on the intermediate layer.
