Abstract
A servo controller for an embedded disk controller comprises a read channel interface that includes a programmable control logic that receives a servo field detected signal from a module that detects a servo field start bit. A memory in the read channel interface is enabled by the programmable control logic for receiving servo field data from a read channel device, wherein the programmable control logic is configured to operate in a first mode and a second mode allowing the servo controller to process servo data from the read channel device. The servo controller processes the servo data using first and second data widths during the first and second modes, respectively.
