Problems solved by technology

[0007] However, in a general optical disc recorder, before performing the above-mentioned data recording operation, it is necessary to run a series of optimal power calculation (OPC) operations for recording text data in the above-mentioned PCA area, for example, as shown in FIG. Optimal power calculation operation cannot be performed when text data is recorded in the above PCA area, so there is a problem that data recording operation cannot be performed even if there is remaining recording space in the data area

Abstract

The invention relates to a data recording method for compact disc recorder. For instance, in disc recorders like a DVD recorder, the optimal power computation is operated before the data recording operation is run. When the data can not be recorded in a power correcting area (PCA) the disposable recorded DVD or the like compact discs, the optimal recording light power value is set according to a beta value after reading the recorded data and detecting the beta value, thus running the data recording operation normally. The invention can prevent the occurrence of data recording error caused by the optimal power computation operation error.

Description

[0001] technology area [0002] The present invention is related to a data recording method in an optical disc recorder, for example, in various types of optical disc recorders such as a DVD recorder (DVD-Recorder), the operation of Optimum Power Calculation (OPC: Optimum Power Calculation) for normal operation prevents data recording Wrong data recording method in the disc recorder. Background technique [0003] In general, in various types of optical disk recorders such as DVD recorders that can record and store high-quality video data and high-quality audio data for a long period of time, DVDs that can record once (such as DVD-R / +R), etc. In the case of recording data on an optical disc, as shown in FIG. 1 , after selecting a PCA (PCA: Power Calibration Area: Power Calibration Area) area allocated in the internal area of ​​the optical disc, an OPC operation is performed. [0004] On the one hand, when the above-mentioned PCA area, for example, n error correction codes (ECC...
