Abstract
A method for tuning a plurality of write strategy parameters of an optical storage device includes detecting a plurality of patterns. Each pattern corresponds to a pit or a land on a phase-changed type optical storage medium accessed by the optical storage device. The method further includes performing calculations corresponding to a plurality of data types and generating a plurality of data-to-clock edge deviations respectively corresponding to the data types. Each pattern belongs to a data type. The data-to-clock edge deviations are utilized for tuning the write strategy parameters corresponding to the data types respectively.
