Systems and methods for using an on-the-fly CBD estimate to adjust fly-height
Various embodiments of the present invention provide systems and methods for using channel bit density estimates to adjust fly-height. For example, various embodiments of the present invention provide methods for adaptively adjusting fly-height. Such methods include providing a storage medium that includes information corresponding to a process data set, and a read/write head assembly that is disposed a variable distance from the storage medium. The process data set is accessed from the storage medium. A first channel bit density estimate is adaptively calculated based at least in part on the process data set and a second channel bit density estimate that was previously calculated. The variable distance is modified based at least in part on the first channel bit density estimate. A third channel bit density is adaptively calculated based at least in part on the process data set and a fourth channel bit density estimate that was previously calculated. The variable distance is modified based at least in part on the third channel bit density estimate.
