摘要

A magnetic recording medium comprising a non-magnetic support, a magnetic layer on one surface of said non-magnetic support, a back coating layer on the other surface of said non-magnetic support and a primer layer containing acicular hexagonal ferrite magnetic powder between said non-magnetic support and at least one of said magnetic layer and said back coating layer, which is used with a video recorder fitted for high density recording and in particular, which copes with prolongation of a recording time.
