DATA RECORDING METHOD AND DATA RECORDING APPARATUS |
摘要 |
A data recording method preferably used to record data on an optical disk such as a DVD+RW disk. If a normal write clock is correctly generated during write of data in a block area (A), the write of data is stopped and a re-allocation of the area (A) is performed. Predetermined data is written in the area (A) by using a reference clock in such a way that the data is written over the areas (A and A+1), thereby preventing any unrecorded portion due to the rotation fluctuation of the optical disk from being generated behind the block (A). Data is written in the area (A+1) by using a normal write clock. Re-allocation of the area (A+1) is also performed. Thus the problem that the tracking servo over the areas (A and A+1) fails is prevented.
