摘要 |
A magnetic recording medium excellent in the strength of the magnetic layer; dispersibility; surface smoothness and electromagnetic conversion characteristics of the magnetic layer; and durability under special conditions is disclosed. A magnetic recording medium of the present invention is such as being obtained by coating, on a non-magnetic support, a magnetic coating material having a magnetic powder and a binder dispersed in a solvent, wherein the binder contains two kinds of polyurethane resins such as an aromatic polyester polyurethane resin obtained by urethanization of an aromatic polyester with an aromatic diisocyanate; and a polyurethane resin obtained by urethanization of a glycol having a molecular weight of 60 to 250 with an aromatic diisocyanate under a condition ensuring a urethane group concentration of 3.0 mmol/g or above.
