摘要:
Disclosed is a magnetic recording medium comprising at least two layers comprising at least one lower non-magnetic layer containing at least a non-magnetic particle and a binder on a non-magnetic support, and at least one upper magnetic layer containing at least a ferromagnetic particle and a binder on the lower non-magnetic layer, wherein a mean total thickness d of the upper magnetic layer is more than 0.01 .mu.m to less than 0.3 .mu.m, and a standard deviation .sigma. of the total thickness of the upper magnetic layer and the mean total thickness d of the upper magnetic layer satisfy the relationship of 0.05.ltoreq..sigma./d.ltoreq.0.5.
