Paper Abstract

The effects of focus misregistration (FMR) on signal amplitude, jitter, write performance, peak shift, and the figure-of-merit parameter were investigated as a function of track position, pattern, write power, and crosstalk. Experimental results for FMR offsets were compared to theoretical predictions. A Monte Carlo model of FMR distribution was generated from experimental results. These results were then compared to results from noise injection into the focus servo. In the test system, the tracking servo failed under focus noise injection before system performance degraded appreciably.
