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 and a first write power; establishing a Pit-to-Land Inter-Symbol Interference table and a Land-to-Pit Inter-Symbol Interference table through measuring a plurality of Pits and Lands with different time lengths in the test pattern; and generating a second overdrive power by adjusting a first overdrive power of the first write strategy according to the Pit-to-Land Inter-Symbol Interference table and the Land-to-Pit Inter-Symbol Interference table.
