Storage media, systems, and techniques for storing and accessing information in a servo band are described. For example, the distances between adjacent servo patterns written to the servo band may be varied to represent the supplemental information stored in the servo band. Each of the varied distances may be selected to represent physical parameters of the storage medium, servo recording conditions, or data unrelated to the servo patterns, for example. The supplemental information may be recovered from the servo band by demodulating a signal generated from a servo read head. The distances between each servo pattern in the track may be calculated from the time periods detected in the signal between servo marks of subsequent servo patterns. In some examples, a controller may adjust one or more parameters associated with reading or writing servo marks or data marks of the storage media. |
