Optical disk and defect management method of optical disk device

Abstract

The present invention relates to a defect management method of an optical disc device and an optical disc based on the same. In the same optical disc device as a digital video disc recorder (DVD-Recorder), on a digital video disc (DVD+R) capable of recording at one time In the middle of recording data, if the recording operation of defect data ends abnormally, the reserved area allocation table (RAST) information corresponding to it is effectively generated and recorded in the specific section allocated by the track allocation in the data area, and the retrieval and playback control Even if the recording operation of the previously normally recorded data is abnormally terminated due to a defect, the data previously normally recorded can be effectively prevented from being damaged, so it is a very useful invention.

Description

【Technical field】 [0001] The present invention relates to a defect management method in an optical disc device and an optical disc based on it, for example, in the same optical disc device as a digital video disc recorder (DVD-Recorder), in a recordable digital video disc (DVD+R) In the middle of recording data, defect (Defect) occurs when the data recording operation is abnormally terminated. A defect management method in an optical disc device and an optical disc based on it in order to be able to read and reproduce data that has been normally recorded before. 【Background technique】 [0002] figure 1 It is a structural diagram of a general optical disc device. For example, an optical disc device similar to a digital video disc recorder may include an optical pickup 11, a VDR (Video Disc Record) system 12, a microcomputer 13, a memory 14, and a menu diagram generation unit. 15 and so on constitute. [0003] On the one hand, in the above-mentioned microcomputer 13, when th...

Problems solved by technology

[0011] However, as described above, in the general optical disc device, in the middle of recording data on a digital video disc that can be recorded at one time, a defect occurs when the data recording operation is abnormally terminated, for example, figure 2 As shown, perform the third recording action (3 rd Recording), if the data recording operation is abnormally terminated due to a defect, the file system and navigation information (FS&NAVI#3) corresponding to it will not be recorded, and the recording reserve area allocation table (RSAT#3) cannot be generated. Therefore, according to the first recording operation and the second recording operation, for the normally recorded data, retrieval and reproduction control cannot be performed.
