Write fault threshold for a set of tracks

摘要

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.

1. An apparatus comprising:
a processor configured to:
determine a position error signal value for a first data track;set a first write fault threshold for a second data track adjacent to the first data track based on the position error signal value and based on the first data track and the second data track sharing a combined write fault threshold amount; andwrite data to the second data track based on the first write fault threshold.
