Abstract
Automatically optimizing and programming features of a disk drive read channel for a selected partial response (PR) target. This enables flexible PR targets to be used in the read channel. The flexible PR targets can have arbitrary coefficients, and the channel features (parameters, functions and algorithms) that are dependent on the flexible PR targets are automatically adapted and programmed in hardware or firmware. With flexible PR targets, the read channel can support longitudinal and perpendicular recording without compromising performance.
