摘要： A magnetic recording media, e.g. VTR tape is improved by comprising an undercoating layer on a polyester film substrate (1), the undercoating layer being formed under a ferromagnetic thin film (4) and being an even-scattering of a large number of inorganic or organic granules (2) scattered at a rate of 1000/mm 2 or more.
