Abstract
A magnetic recording medium is disclosed, comprising a nonmagnetic support having thereon a magnetic layer, said magnetic layer comprising ferromagnetic particles and a binder, wherein nonmagnetic support has a transverse-direction Young's modulus of at least 1,000 Kg/mm.sup.2, said magnetic layer has a glass transition temperature of 80.degree. to 100.degree. C., and said magnetic recording medium has a total thickness of less than 12 .mu.m, and further a magnetic recording medium is disclosed, comprising a nonmagnetic support having thereon a magnetic layer, said magnetic layer comprising ferromagnetic particles and a binder, wherein said magnetic recording medium is adapted for use with a magnetic head having a core width of at least 100 .mu.m at a speed of at least 20 m/sec based upon relative speed of said recording medium and said head, said nonmagnetic support has a transverse-direction Young's modulus of at least 1,000 Kg/mm.sup.2, said magnetic layer has a glass transition temperature of from 80.degree. to 100.degree. C., and said magnetic recording medium has a total thickness of less than 12 .mu.m.
