The invention is directed to a data storage medium that includes a
plurality of servo bands distributed across the data storage medium and a
plurality of data tracks positioned between each of the plurality of
distributed servo bands. The data storage medium comprises a servo band
pitch of less than 200 micrometers. The large number of servo bands
distributed across the data storage medium with a relatively small servo
band pitch reduces the influence of media dimensional instability. In
this way, the invention may substantially increase data read head
positioning accuracy, especially in the case of narrow track widths. A
read head array arranged in a two-dimensional matrix that includes a
first servo read head, a second servo read head, and a plurality of data
read heads positioned between the first and second servo read heads may
be applied to a data storage medium as described herein.
