Abstract
Methods and apparatus are provided related to magnetic recording tape. Respective voltage sources are coupled to respective magnetic head components of a tape recording apparatus. Circuitry controls each voltage source independently in accordance with identity information for a magnetic tape, relative humidity within the tape recording apparatus, or other factors. Chemical migration from the tape, and/or plating or erosion of elements of the tape recording apparatus are substantially reduced or eliminated according to the present teachings.
