Abstract
An apparatus includes a tape read head bias signal control circuit configured to present to a tape read head a first amplitude bias signal in response to at least a first control signal and a second amplitude bias signal in response to at least a second control signal, wherein the second amplitude is lower than the first amplitude. The read head, thereby, may have a reduced operating temperature.
