Abstract
A method and system for servo stripe width detection and compensation including moving a magnetic tape in a first direction across a magnetic tape head, the magnetic tape having a servo band including a first servo pattern and a second servo pattern, the magnetic tape head having a servo element; detecting a leading edge and a trailing edge of the first servo pattern with the servo element; detecting a leading edge and a trailing edge of the second servo pattern with the servo element; determining a first time from the leading edge of the first servo pattern to the leading edge of the second servo pattern; determining a second time from the trailing edge of the first servo pattern to the trailing edge of the second servo pattern; and determining a correction value from a difference between the first time and the second time.
