摘要：
A dual-layer magnetic recording tape having a non-magnetic substrate with a front side and a back side, a lower support layer formed over the front side and a magnetic recording layer formed over the lower support layer. The magnetic recording layer includes magnetic metallic pigment particles having an average particle length up to about 35 nm, and a coercivity of at least about 2,000 Oersteds. The magnetic tape has a BB noise less than about −91 dB at about 93 kfci.
