Abstract
According to the present method a plurality of vertically adjacent reference tracks corresponding to a plurality of vertically adjacent data tracks are written to the tape media so that each data track includes a dedicated reference track that is used to locate that data track. To locate a desired data track, the tape head assembly is used to locate a boundary between a reference track corresponding to a desired data track and an adjacent reference track. Using the boundary as a reference point, the tape head assembly is aligned with the desired reference track and the tape media wound through the tape path to read or right data to the corresponding track.
