用于在多层记录介质中监测和管理激光功率校准区域的记录和再现装置和方法

Recording and reproduction apparatus and method for monitoring and managing laser power calibration areas in a multi-layer recording medium
Abstract:
Medium recording and reproduction apparatus and method can prevent prohibition of disc recording due to the fact that laser power calibration area becomes unusable by studying a management information update method during data recording. When usable capacity of the laser power calibration area is monitored and the capacity is reduced, management information area to be currently updated is changed to another layer.
