Research output: Contribution to journalArticlepeer-review


Discrete track media were simulated and compared with conventional, continuous media. The optimum write pole width was determined for discrete track media with 60 nm land/30 nm grooves, subject to the condition that there be no adjacent track erasure. Under optimal conditions discrete track media outperformed continuous media in terms of both on-track and off-track SNR. The performance difference became greater at higher linear densities, demonstrating the potential of discrete track media.
