Abstract
The disclosure is related to apparatuses and methods for characterizing and compensating for curvature in a write field generated by a data storage device transducer. In some embodiments, the curvature of a write field generated by a data storage device transducer may be characterized. Some embodiments can include a circuit to apply a phase compensation value based on a deterministic phase offset value, which may correspond with the write field curvature characterization.
