Abstract
Identification of servo tracks is provided by adding one or more additional symbols to the write elements of at least some tracks on a servo recording head. The additional symbols are ignored for timing purposes, as they are not necessarily symmetrical, but the added symbols provide identification by their alterations on the otherwise identical patterns.
