Abstract:
A method is presented for setting a wrap angle of a read/write head having a servo element and multiple read elements, where the servo element and the read elements can detect a servo signal. The method includes moving a sequential information storage medium having a longitudinal axis and a servo band encoded therein adjacent to the read/write head. The longitudinal axis and a flat upper surface of the read write head define the wrap angle. The method further includes detecting the servo signal using one of the read elements. If the read element is unable to detect the servo signal, then the remaining read elements are sensed to detect the servo signal.
