As two key restrictions for increasing the recording capacity, cross-erase and jitter from narrowing track pitch (0.55μm-0.6 μm) and making small marks (0.40μm-0.62μm) are presented using a thermally optimum phase-change optical disk with the ability of thermal endurance and high thermal conduction as well as minimum crosstalk and maximum groove signals. For overwriting jitter no increase after 104 cycles is observed. The cross erase after 101 overwriting cycles resulted in less than 1% of jitter increase from the initial value.
