Abstract: A magnetic recording medium including a non-magnetic substrate and a magnetic coating. The non-magnetic substrate defines a front side and a backside. The magnetic coating is formed over the front side and is characterized by an Abrasivity Index of not greater than 350 microinches. In one preferred embodiment, the magnetic coating includes a lower layer formed on the front side of the substrate, and an upper layer formed over the lower layer. In this regard, the upper layer includes a magnetic metal particle dispersed in a binder and otherwise provides the Abrasivity Index. In another embodiment, the magnetic recording medium is a DLT tape.

Abstract: A magnetic recording medium including a non-magnetic substrate, a back coat, a lower layer, and a magnetic upper layer. The substrate defines a front side and back side, with the back coat being formed on the back side. The lower layer is disposed over the front side of the substrate and includes a primary powder material and conductive carbon black material dispersed in a binder. The primary lower layer powder material comprises particles having a coercivity of less than 300 Oe coated with an electroconductive material. The magnetic upper layer is disposed over the lower layer and includes a magnetic powder dispersed in a binder.

Abstract: A multi-layer magnetic recording medium and a method for making a multi-layered magnetic recording media as described. The recording medium has magnetic inner layer with magnetic particles having a specific squareness ratio and saturation magnetization which results in superior high frequency output and improved overwrite characteristics. The method for making a magnetic recording medium involves controlled, partial drying of the inner layers to avoid intermixing of the respective layers while facilitating efficient fabrication.
