Abstract
The present invention relates to a method of maintaining an optimal writing power for various recording modes during data recording onto a recording medium. The present method checks a recording speed at a recording position, reads a write strategy set for the checked recording speed, detects a reflected level while recording data with the read write strategy, and changes a level reference for ROPC according to the detected level. Accordingly, a writing power can be kept most optimal even though a recording speed changes during data recording, thereby improving the quality of reproduced signals.
