Abstract
A sequential data storage medium, such as for example and without limitation a magnetic tape, comprising a plurality of servo patterns encoded in a non-data region, wherein each of said servo patterns comprises a first subframe comprising 10 pulses, a second subframe comprising 8 pulses, and a third subframe comprising (N) pulses, wherein (N) is greater than or equal to 0. The first subframe and the second subframe do not encode any linear position (“LPOS”) data. The third subframe encodes up to (N) LPOS bits.
