ABSTRACT:
Embodiments of methods and apparatus for compensating writing power in an optical disc device can compensate selected (e.g., OPC) writing power. When a writing operation is temporarily suspended (e.g., buffer under-run) during the writing operation, writing power is compensated in real time on the basis of the β value detected from read RF signals for most recently recorded data and comparisons to selected writing power (e.g., optimum β value stored therein through OPC).
