Decreasing track pitch using shingled writing

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, the feasibility of two-dimensional magnetic recording is discussed from the viewpoint of high track density. 747 curves of shingled track were measured using existing heads and media and were interpreted with a squeezing model dominated by the SN ratio of the read head output. As long as a reader can be placed on the median line of the squeezed data area, wider OTC than that of conventional writing will result. The modeled 747 curves were in good agreement with the experimental data for both conventional writing and shingled writing. Consequently, reduction of erase band widths is important in the case of shingled writing even if the erase band width is reduced on only one side. By skewing head, reduced erase band width is accomplished.
