METHOD OF ADJUSTING WRITING PARAMETERS, OPTICAL DISC WRITER AND METHOD OF RECORDING DATA USING THE SAME

摘要

The present invention discloses a method of adjusting writing parameters, comprising the steps of testing a region to be written in a re-writeable optical disc without changing writing power level; calculating writing parameters in the region to be written based on the tested result; S130 and adjusting writing parameters based on the calculated result S140. According to embodiments of the present invention, the direct over writing compatibility problem can be resolved. Moreover, power level adjusting is kept unchanged so as to avoid possible damage to direct over writing cycleability.
