Abstract
A magnetic recording medium comprising a non-magnetic transparent support, a magnetic layer, and a conductive intermediate layer formed between the non-magnetic transparent support and the magnetic layer, the conductive intermediate layer comprising, as major components, powder of conductive metal or metal compound and a binder resin, wherein: the binder resin of the intermediate layer contains from 10 to 200 .mu.eq/g of --SO.sub.3 M group, --COOM group, --PO.sub.3 M.sub.2 group, or --NH.sub.3.sup.+ X.sup.- group, where M is a hydrogen atom, an alkali metal atom, or an alkaline earth metal atom, and X is a monovalent anion, and the ratio of the content of the powder of the conductive metal or metal compound to that of the binder resin, based on weight, in the conductive intermediate layer is from 8 to 13, and a recording/reproducing method.
