Record end action executing method for CD device

Abstract

The present invention is the record end action executing method for CD device and relates to the field of PCA of CD. The method can end record automatically without needing the user's additional key value. The present invention consists of the step of affirming the total OPC executing number during inserting the CD; and the second step of automatically executing preset record end related action based on the different between the affirmed total OPC executing number and maximum executable number. The method makes it possible to avoid maloperation without record end mark caused by careless recording.

Description

(1) Technical field [0001] The present invention relates to a recording end action execution method of an optical disc device, in particular to the PCA field of optical discs, which can automatically execute the recording end (Finalize) action without the user inputting another key value. (2) Background technology [0002] In the existing optical disc device, when a recordable optical disc (for example, CD-R) is inserted in the device, the operation OPC (Optimal Power Calibration) for detecting the optimal recording optical power utilized during recording is performed, that is to say, in figure 1 The test field (A) in the PCA field of the optical disc shown was about 15 ATIP recording test data, and the optimum recording optical power was detected from its playback characteristics. Then, after such test data recording is completed, record empty data (null data) through 1ATIP again in the calculation field (B) in the above-mentioned PCA field, so as to indicate that the OPC a...

Problems solved by technology

[0005] However, in the past, the user could not confirm the number of OPC executions in the PCA area. If the user has executed 100 OPC actions in the PCA area and could not finalize the recording on the disc, for such a record that has not been finalized (Finalize) The optical disc has the temporary recording information of the playback disc only in the temporary recording information area PMA (Program Memory Area), and there is no playback directory information TOC (Table Of Contents) in the lead-in area (Lead-in) area.

[0006] Therefore, on an ordinary CD-ROM that uses TOC information to perform playback operations, there is a problem that such a disc that has not been recorded (Finalized) cannot be played.
