Patent ID: 7577067

Claim:
A method of controlling a recording operation of a recording medium, comprising: in response to a recording request from a user, determining whether power levels associated with at least two previous optimum power calibration (OPC) operations associated with a common drive are recorded on the recording medium; if power levels associated with at least two previous optimum power calibration (OPC) operations are recorded on the recording medium, calculating a difference between power levels associated with the at least two previous optimum power calibration (OPC) operations to generate a difference value; if the difference value is less than a predetermined reference value, recording information on the recording medium with a power level of a latest of the at least two previous optimum power calibration (OPC) operations; and if the difference value is greater than the predetermined reference value, calculating a mean power value of the at least two previous optimum power calibration (OPC) operations and recording the information on the recording medium with the calculated mean power level.
