Embodiment Construction
[0070] The invention can be used to optimize both write strategies. 1 a and FIG. 1 b are schematic diagrams of exemplary write strategies for programming pits, respectively an exemplary castle type write strategy and an exemplary multipulse type write strategy. Referring to Figure 1a, P w Represents the laser power, P OD (overdrive) represents the overdrive value of the short pattern amplification power ratio, S k and E k respectively represent the increasing width of the leading edge of the short pattern and the increasing width of the trailing edge of the short pattern. The short patterns may include patterns of 3T to 5T. In another embodiment, P w ,P OD , S k and E k Used to write long patterns from 5T to 11T, 14T. In this embodiment, the write strategy parameter P w ,P OD , S k and E k Represents a static write policy parameter. Static writing strategy parameters are related to whether the pattern can be formed and the quality of the formation. In addition, ...
