Estimating the term…
An apparatus, system, and method are disclosed for dynamically controlling a recording head substrate bias voltage. The apparatus includes a midpoint module and a substrate module. The midpoint module calculates a midpoint voltage of a plurality of data read elements and servo read elements contained in the head. The substrate module calculates a substrate bias voltage. The apparatus, system, and method dynamically control the substrate bias voltage post-assembly, minimizing certain head degradations and extending the life of associated head readers.
An apparatus to dynamically control a substrate bias voltage, the apparatus:
A system to dynamically control a substrate bias voltage, the system comprising:
A signal bearing medium tangibly embodying a program of machine-readable instructions executable by a digital processing apparatus to perform operations to dynamically control a substrate bias voltage, the operations comprising:
