Magnetic recording media having a backside coating which includes multicomponent, nonmagnetic particles.

摘要

A magnetic recording medium comprising a support having two major surfaces, a magnetic layer provided on one major surface of the support, and a backside coating provided on the other major surface of the support wherein the backside coating comprises nonmagnetic, multicomponent particles dispersed in a polymeric binder. The nonmagnetic, multicomponent particles are comprised of a first component having a Mohs hardness equal to or less than 7 and a second component having a Mohs hardness greater than 7.
