摘要：
A magnetic recording medium comprising a flexible support and a magnetic layer formed on the flexible support. The flexible support is made of a resin composition which comprises thermoplastic resins and particles of titanium monoxide or dititanium trioxide. The particles are dispersed in the thermoplastic resin in an amount of 0.03 to 10 wt % of the composition and have an average size below 2.5 .mu.m.
