Systems and Methods for Zone Servo Timing Gain Recovery |
摘要 |
Various embodiments of the present invention provide systems and methods for data processing. As an example, a data processing system is disclosed that includes Various embodiments of the present invention provide data processing systems that include an analog to digital converter circuit and a phase and gain computation circuit. The analog to digital converter circuit is operable to convert an analog input into a series of digital samples. At least a portion of the series of digitals samples represent a periodic signal from a servo data region. The phase and gain computation circuit is operable to: determine an approximate amplitude of the periodic signal based at least in part upon the digital samples representing the periodic signal from the servo data region; determine a gain based at least in part on the approximate amplitude; and determine a phase based at least in part on the approximate amplitude.
