Magnetic recording medium

摘要

A magnetic recording medium exhibiting not only good durability and traveling reliability but also improved static magnetic properties and electromagnetic transduction characteristics can be obtained according to the present invention. The magnetic recording medium includes a non-magnetic substrate and a magnetic layer composed of a magnetic powder, a binder and a lubricant, wherein the binder contains not less than 50% by weight of a polyester-polyurethane resin having a number-average molecular weight (Mn) of not greater than 15,000 and a ratio of a weight-average molecular weight (Mw) to the number-average molecular weight (Mn) of not smaller than 2.5.
