Many view data storage on patterned magnetic media as one way of attaining storage densities in excess of 1 Tb/in/sup 2/ and thus overcoming the problems associated with recording at ultrahigh densities on conventional continuous media. In this paper we investigate, through the use of a replay simulation developed to take into account the three-dimensional nature of the patterned media, the effects that the shape-constrained media have on the bit-error-rate performance of the read channel in 1-Tb/in/sup 2/ perpendicular recording. In particular, we analyze how media configurations with varying island shape, size, and distribution affect the channel performance.
