Patent ID: 7348079

Claim:
A magnetic recording medium comprising: a non-magnetic support, and provided in order on the support: a radiation-cured layer formed by curing a layer containing a radiation curing compound by exposure to radiation, wherein the molecular weight of the radiation curing compound is 1,000 or less; a lower layer comprising a non-magnetic powder and/or a magnetic powder dispersed in a binder; and at least one magnetic layer comprising a ferromagnetic powder dispersed in a binder; the binder of at least the magnetic layer comprising a binder having a glass transition temperature of 100° C. to 200° C., and the at least one magnetic layer having on the surface thereof a number of micro projections having a height of 10 to 20 nm measured by atomic force microscopy (AFM) of 5 to 1,000/100 μm 2 , and the at least one magnetic layer having a thickness of 0.05 to 1.0 μm.
