Abstract
A data storage device, e.g., a disc drive, includes one or more heads including a transducer. Each head also includes a deformable material that allows the spacing adjustments between the transducer and a data storage medium, e.g., a data storage disc, according to each of a plurality of settings. The device calculates a response function of a spacing change to a setting change for each head by measuring a change in the pole tip-data storage medium spacing corresponding to at least two settings. The device also determines an optimal setting. The device may also repeat response function calculations and/or determination of optimal settings to ensure continued optimal performance of the device. In summary, the device sets an optimal setting for each head according to a calculated response function particular to each head.
