Abstract:
1. A method for adaptively adjusting fly-height, the method comprising: providing a storage medium, wherein the storage medium includes information corresponding to a process data set; providing a read/write head assembly, wherein the read/write head assembly is disposed a variable distance from the storage medium; accessing the process data set from the storage medium; adaptively calculating a first channel bit density estimate based at least in part on a second channel bit density estimate calculated prior to the first channel bit density estimate and the process data set; modifying the variable distance based at least in part on the first channel bit density estimate; adaptively calculating a third channel bit density estimate based at least in part on a fourth channel bit density estimate calculated prior to the third channel bit density estimate and the process data set; and modifying the variable distance based at least in part on the third channel bit density estimate.
