Abstract
In one embodiment, a magnetic data storage apparatus includes a magnetic head having at least one group of N servo readers, a drive mechanism for passing a linear magnetic recording medium over the head, and a controller electrically coupled to the head. The controller is configured to position a first servo reader of the at least one group of N servo readers in a first lateral medium region of the recording medium with a servo band having a width b that is less than or equal to about 1.2 B/N, where N is an integer greater than or equal to 2, and B corresponds to a distance between data read/write transducers of the magnetic head, and position the magnetic head in a second lateral region of width b with a second servo reader of the at least one group of N servo readers for reading the servo band.
