Magnetic recording medium

摘要

Provided is a particulate magnetic recording medium with good output at high frequency, yielding a low coefficient of friction, and having good running properties, in particular, a magnetic recording medium affording good electromagnetic characteristics and good repeat durability in recording and reproducing at a high-density. The magnetic recording medium comprises a lower layer comprising a nonmagnetic powder and a binder and an upper magnetic layer comprising a ferromagnetic powder, a binder and at least one abrasives provided on a nonmagnetic support in this order. The number of abrasive particles present on said magnetic layer surface satisfied the relation 0.2 ). When the number of pairs of abrasive particles satisfying the relation L ), Y/X is equal to or less than 2.
