Abstract

The disclosed magnetic recording servo pattern improves the detection of Gray code fields when implemented with a narrow bandwidth channel. Baseline disturbances are minimized by limiting the maximum time between magnetic transitions. The pattern discussed limits magnet lengths to a ratio of 2 to 1.
