METHOD OF ADJUSTING WRITE STRATEGY OF RECORDABLE DISC |
摘要 |
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 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; generating an updated overdrive power by adjusting an 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; and defining a second write strategy according to the updated timing parameter set and the updated overdrive power.
