US Patent 7636284 Method for compensating writing power in optical disc device

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).
