A magnetic recording medium for storing digital data includes a flexible substrate, a first magnetic side, and a second magnetic side. The flexible substrate defines a first surface and a second surface opposite the first surface. The first magnetic side has a resistivity of less than about 2x106 ohms/square and includes a first support layer and a first magnetic layer. The first support layer is substantially non-magnetic and extends over the first surface of the substrate. The first magnetic recording layer extends over the first support layer opposite the substrate. The second magnetic side includes a second support layer and a second magnetic layer. The second support layer is substantially non-magnetic and extends over the second surface of the substrate. The second magnetic recording layer extends over the second support layer opposite the substrate.
