Magnetic recording medium
 A novel magnetic recording medium comprising a non-magnetic support, a magnetic recording layer, and an intermediate layer containing an electroconductive polymer. An optional second intermediate layer contains carbon black and is provided on either surface of the first intermediate layer. The magnetic recording medium has low surface electric resistance, and when used as a video tape, has both a high video S/N ratio and improved stability of video S/N with the passage of time.
