Predictive methods and systems for sampling data read from a rotating storage medium
Abstract:
A read and write system comprising a mark detection module, an offset estimation module, and a frequency adjustment module. The mark detection module is configured to generate (i) a first mark indicator when first servo data is read from a storage medium, and (ii) a second mark indicator when second servo data is read from the storage medium. The offset estimation module is configured to estimate at least one of a first distance or an offset angle based on (i) a first location of the storage medium, and (ii) a period between times when the first mark indicator and the second mark indicator are generated. The frequency adjustment module is configured to adjust a sampling frequency at which user data is read from the storage medium based on the at least one of the first distance or the offset angle.
