Abstract:
1. A system for efficiently determining a position error of a head in relation to a storage medium, the system comprising: a storage medium including a series of data; wherein the series of data includes a first defined marker and a second defined marker located a distance from the first defined marker, and wherein the series of data further includes position location data; a first detector circuit operable to detect the first defined marker and to establish a location of the first defined marker; a second detector circuit operable to detect the second defined marker and to establish a location of the second defined marker; an error calculation circuit, wherein the error calculation circuit is operable to calculate an interpolation offset based at least in part on the location of the first defined marker and the location of the second defined marker; and an interpolation circuit, wherein the interpolation circuit is operable to interpolate the position location data and to provide an interpolated position location data.
