Abstract
A systematic experimental study of reverse overwrite (ReOVW) process in the shingled recording scheme has been conducted in conjunction with characterization of corresponding recording performances from recording heads with different geometries. It was found that not only is there no ReOVW reduction as the track density increases, but also ReOVW is, in fact, slightly increased from 300 ktpi to 600 kpi or beyond by using the same writing conditions. These data suggest that conventional magnetic recording technology might be able to extend all the way beyond an areal density of one Tbit/in2 by using the shingled recording scheme.
