Patent ID: 8233363

Claim:
A method of controlling a recording operation, the method comprising: setting recording power and parameters related to the generation of recording pulses for a disc by successively performing: an optimum power controlling (OPC) process for adjusting recording power; and an optimum write strategy (WST) tuning control (OWC) process for adjusting parameters related to the generation of recording pulses, determining whether the disc is a non-universal disc or a universal disc, and in response to determining that the disc is a non-universal disc, adjusting WST information corresponding to the disc based on the parameters adjusted by the OWC process; and performing data recording on the disc based on the set recording power and the set parameters related to the generation of recording pulses, wherein the adjusting of the WST information is based on whether an identification (ID) of the non-universal disc is included in a group of non-universal disc IDs stored in a memory.
