Abstract
A headerless, fault-tolerant sample-data servo pattern, comprising an alternating sequence of first and second servo sectors, with the first servo sectors each including a partial track address and circumferential orientation information, and the second servo sectors each including a full track address, provides an absolute indication of a read/write head's circumferential orientation along a given track on a magnetic disk which is robust in the presence of defects in the magnetic recording medium.
