Video recording tapes suitable for high speed contact duplication

A magnetic recording medium, comprising

• a nonmagnetic substrate having a first and a second major surface,
• a magnetic layer provided on the first major surface of the substrate, comprising a first polymeric binder, a magnetic pigment, and one or more nonmagnetic pigments, wherein the total amount of pigment is at least 80 percent by weight of the magnetic layer,
• a backside coating provided on the second major surface of the substrate, comprising two nonmagnetic pigments dispersed in a second polymeric binder, the first nonmagnetic pigment having a particle size of between 0.015 and 0.15 .mu.m, and the second nonmagnetic pigment having a particle size of between 0.15 and 1.5 .mu.m,
• wherein the magnetic layer has a lubricant absorption value of at least 4 and a surface roughness Rq of less than 15 nm, and the backside coating has a surface roughness Rq of between 15 and 150 nm, wherein the magnetic recording medium is a tape having a relative backside slippage between 71 and 83 percent and a magnetic/backside slippage ratio of at least 0.9.
