ABSTRACT:
A method of adjusting a write strategy of a recordable disc comprises steps of: generating a test pattern on a power calibrating area of the recordable disc according to a first write strategy, a first write power, and a first target β value; establishing a Pit-to-Land Inter-Symbol Interference table and a Land-to-Pit Inter-Symbol Interference table by measuring a plurality of Pits and Lands with different time lengths in the test pattern; generating an updated timing parameter set by adjusting a timing parameter set of the first write strategy according to the Pit-to-Land Inter-Symbol Interference table and the Land-to-Pit Inter-Symbol Interference table; and generating an updated target β value according to the updated timing parameter set.
