Magnetic recording media having increased skirt signal-to-noise and carrier-to-noise ratios |
摘要 |
A dual-layer magnetic recording medium including a non-magnetic substrate having a front side and a back side, a lower support layer formed over the front side and a magnetic upper recording layer formed over the lower layer, wherein the magnetic layer contains magnetic metallic pigment particles having a coercivity of at least about 2500 Oersteds (Oe), and a binder system for the pigment. The magnetic recording medium exhibits significantly improved broadband signal-to-noise, and skirt signal-to-noise ratios, as well as an improved high frequency carrier-to noise ratio.
