摘要： A system in an optical storage device has a controller which obtains a plurality of write strategy parameters for the optical storage device to write data on an optical storage medium. The write strategy parameters are derived from data-to-clock edge deviations respectively corresponding to a plurality of data set types. Each of the data set types corresponds to a combination of at least a specific target pit length and a specific target land length, or a combination of at least a specific target land length and a specific target pit length.
