ABSTRACT:
A magnetic recording medium which comprises a base film having a multitude of fine projections uniformly distributed over one surface thereof, and a magnetic layer formed on the base film. The magnetic layer is made of magnetic acicular particles extending from the individual projections in a vertical direction with respect to the base film, and a resin composition comprising a lubricant. The resin composition fills substantially all gaps formed among the vertically extending magnetic acicular particles. This medium may be formed on another magnetic recording medium for longitudinal recording.
