Magnetic recording medium |
| abstract |
A magnetic recording medium having improved running properties and electromagnetic characteristics is disclosed, which comprises a non-magnetic support having provided thereon an underlayer and a magnetic layer composed of a thin ferromagnetic metal film in that order, said underlayer being composed mainly of a high molecular weight compound having on the surface thereof an uneven orange peel texture, wherein said underlayer has an average surface area of a unit cell of the uneven orange peel texture of from 3x10-6 to 3x10-3 mm2, and has a surface roughness of from 0.1 to 0.01 mu m. |
