Abstract:
1. A storage device, the storage device comprising: a storage medium, wherein the storage medium is operable to maintain information corresponding to a process data set; a read/write head assembly disposed in relation to the storage medium; and an adaptive channel bit density estimation circuit, wherein the adaptive channel bit density estimation circuit is operable to receive the process data set via the read/write head assembly, wherein the adaptive channel bit density estimation circuit is operable to compute a first channel bit density estimate of a bit density of the storage medium based at least in part on a first portion of the process data set, and wherein the adaptive channel bit density estimation circuit is operable to compute a second channel bit density estimate of a bit density of the storage medium based at least in part on the first portion of the process data set, a second portion of the process data set and the first channel bit density estimate.
