“…A practical code for this case is an "asymmetric-RLL" code of the form ͑d 0 ,k 0 ,d 1 ,k 1 ͒, where k is the maximum run-length. A suitable example would be a ͑1,7,2,7͒ code, 13 which has a capacity ͑maximum possible efficiency͒ of 0.7966 and for which a practical code exists with a rate ͑efficiency͒ of 0.75. Given that the symbol is half the tip width, the density gain with respect to the uncoded case ͑i.e., assuming one bit per tip width and no RLL constraints͒ is 2 ϫ 0.75, or 1.5.…”

A mark-length write strategy for multiterabit per square inch scanned-probe memories is described that promises to increase the achievable user density by at least 50%, and potentially up to 100% or more, over conventional approaches. The viability of the write strategy has been demonstrated by experimental scanning probe write/read measurements on phase-change (GeSbTe) media. The advantages offered by adopting mark-length recording are likely to be equally applicable to other forms of scanned probe storage.
