Method and apparatus of recording data optimally onto a speed-changing disk

摘要

The present invention relates to method and apparatus of recording data onto a disk recording medium in zoned-CLV mode while adjusting recording speed and recording condition adequately at every speed change point between zones. The present invention detects a current recording position while recording data along a track of the disk recording medium, adjusts a recording speed and resets both a write strategy and a base B-level used for running OPC to be suitable for the adjusted recording speed. The present invention can record input data onto a writable disk with the most suitable writing condition at the highest allowable speed.
