Off-Track Capability Simulation of Shingled Magnetic Recording Under Mechanical Track Misregistration

Shingled magnetic recording (SMR) is suitable for higher density recording due to its writing ability. We calculate the SMR´s offset error rate with a probabilistic approach by using a linear geometric model. The results show the SMR´s offset error rate as being a little better than conventional recording. We also quantify the error rate degradation of multiple adjacent track erasures in conventional recording, which is the largest merit of shingled recording.
