A method of representing a serpentine track accessing format includes
obtaining a plurality of head and physical track number pairs in the
serpentine track accessing format. Then, each of the head and physical
track number pairs are mapped to a unique virtual track number. In some
embodiments, the unique the virtual track numbers are in a non-continuous
monotonic order. In some embodiments, the unique virtual track numbers
are assigned based upon a modulo M which is a function of a maximum
number of tracks per physical zone. Translation engines which perform the
mapping, as well as data storage systems which include the translation
engines, are also disclosed.
