Abstract
Systems and methods are disclosed having a write fault threshold for a set of tracks. A set of tracks may have a shared write fault threshold budget, and a write fault threshold for the second track may be selected based on the shared budget reduced by an off-track position error signal value of the first track. In certain embodiments, an apparatus may comprise a processor configured to determine a position error signal value for a first data track, set a write fault threshold for a second data track adjacent to the first data track based on the position error signal, and write data to the second data track based on the write fault threshold.
