摘要： A method for setting a laser power of an optical disc drive is provided. To perform a label-printing operation on a label surface of an optical disc, an optical pickup unit is shifted to a control feature zone of the label surface, and a laser power operation is performed prior to initiating label printing using power setup data and sensitivity related to an internal laser diode sensor of the optical pickup unit detected during manufacture of the optical disc drive. Alternatively, power setup data associated both a data surface and a label surface of the optical disc may be detected and stored during manufacture of the optical disc drive, and a laser power of predetermined magnitude may determined based on the power setup data previously stored in association with the seated surface of the optical disc. The power setup data may be represented by a substantially linear equation relating the input voltage to the output laser power. Therefore, an optimum laser power for a label surface may be determined prior to actually printing an image on the label surface, thus minimizing error associated with the output laser power, and enhancing label-printing quality.

摘要： A method and an apparatus for setting a laser power of an optical disc drive is provided. A microprocessor (50) determines whether a seated surface of an optical disc (10) is a label surface, shifts the optical pickup unit (30) to the control feature zone of the optical disc (10), sets an output laser power, calculates a target FPDO(Front Phto Detecting Output) value corresponding to the output laser power based on previously stored sensitivity data associated with a laser diode of the optical disc drive, calculates an input voltage corresponding to the output laser power based on previously stored power setup data, detects an current FPDO value corresponding to the input voltage, compares the current FPDO value with the target FPDO value, and maintains or increases the output laser power based on a result of the comparison. Therefore, an optimum output laser power for a label surface may be determined without forming an image on the label surface, and can minimize error of the output laser power, and enhance a label-printing quality.
