摘要：
A magnetic recording medium is described, comprising a non-magnetic support having provided thereon a magnetic layer containing ferromagnetic particles and a binder, wherein said ferromagnetic particles have a tabular ratio (table diameter/table thickness) of 2 or more, a table diameter of from 0.01 to 10 .mu.m, and a lamination degree of the magnetic particles in the magnetic layer in a cross-section thereof of 2 or more.
