A Spinstand Study in Determining the Optimum Shingling Percentage for Shingled Write Recording

One new technology in magnetic recording, shingle write recording, has recently received attention from many researchers as it is one of the candidates to extend the perpendicular magnetic recording. In this paper, we determine and propose the optimum shingling percentage experimentally using various write width head samples with various shingling or overlapping track pitches. We analyze and evaluate the performance characteristics of key parameters that would affect the write ability of the shingled write recording.
