摘要 |
An information storage medium on which data is recorded after performing optimum power control (OPC) and a method and apparatus to record/reproduce data on/from the information storage medium, wherein the recordable information storage medium has a plurality of recording layers and a pickup irradiates a beam onto the information storage medium, utilize operations of: recording data on at least a portion of a recording layer through which a test beam to find an optimum recording power passes before performing optimum power control (OPC) on a desired recording layer and performing OPC on the desired recording layer.
