Optical recording/playback apparatus and method for adjusting playback parameters thereof

摘要

An optical recording/playback apparatus and a method for adjusting playback parameters of the optical recording/playback apparatus are disclosed. The method includes loading an optical disc, determining whether there is data recorded on a data zone of the optical disc, recording test data on an optimal power control (OPC) zone on a playback parameter adjustment area of the optical disc at a reference power when there is no data recorded in the data zone, and adjusting a playback parameter while reading the playback parameter adjustment area, and recording data in the data zone after the adjustment.
