MAGNETIC RECORDING MEDIUM

摘要

In a magnetic recording medium spherical particles (5) are added in a surface magnetic layer (3) of a magnetic film (6) having multilayer configuration (structure). The spherical particles (5) have a diameter in the range of from 0.5 to 1.5 times as large as the thickness of the surface magnetic layer (3), and the amount of the spherical particles (5) is in the range of from 0.1 parts to 1 part per 100 parts by weight of magnetic powder included in the surface magnetic layer (3). Fine studs are formed by the spherical particles (5) on the surface of the surface magnetic layer (3), and it results in both small surface roughness and low coefficient of friction. <IMAGE>
