A statistical investigation of off-track errors for shingled and conventional writing was carried out to reveal the behavior at high track densities. The remanent data width in shingled writing was wider than that in conventional writing for the same average track pitch. Comparison of the distributions of the calculated remanent data width showed that for conventional writing erroneous tracks were generated when the track was squeezed by both neighboring tracks, i.e., double-squeezing. Shingled writing has an advantage in that this double-squeezing does not occur and therefore a higher track density is achievable.
