    摘要： A scratch erasure resistant perpendicular magnetic recording medium comprises a non-magnetic substrate having a surface, and a layer stack formed over the surface and comprising: (i) at least one magnetically hard perpendicular magnetic recording layer; and (ii) at least one low shear modulus layer comprising at least one material having a shear modulus not greater than about 30 GPa. Preferably, the at least one magnetically hard perpendicular magnetic recording layer includes at least a first layer comprised of a magnetic material having a hexagonal close packed (hcp) crystal structure and preferred basal plane crystallographic orientation with c-axis perpendicular to a surface thereof.

    摘要： Oriented longitudinal magnetic recording media on direct texture glass or glass-ceramic substrates with a film structure of one or more Ni-containing layer, a Cr-containing underlayer, a Co-containing magnetic layer and carbon overcoat exhibits are capable of achieving Mrt OR of >1.5, preferably >1.85. Such highly oriented glass media shows a significant SNR (>2 dB) and parametric improvement over the counterpart isotropic media with the same film structure on non-textured glass or glass-ceramic substrates.
