Method of recording and reproducing data

Abstract

The invention relates to a data recording and reproducing method. In the embodiment of the present invention, if a recording failure occurs during the recording of data in the recording medium, then the management information of the previously normally recorded data will be generated and temporarily stored, and the data will be continuously recorded from the next recordable position. If the recording ends normally, the management information of the data recorded after the failure is generated, linked with the temporarily stored management information, and recorded in the recording medium. The data recorded before the recording failure and the data recorded after the recording failure are managed using different titles, and information for linking and reproducing the title before the recording failure and the title after the recording failure can be added to each title. in the management information.

Description

technical field [0001] The invention relates to a data recording and reproducing method. Background technique [0002] Recently, optical disk devices capable of recording audio and video data input in real time have become popular and widespread. Broadcast programs received through the tuner or moving image data input through external terminals are compressed into MPEG data streams by compression methods such as MPEG-1 / 2, and recorded in real time on CD-R / RW, DVD-R / +R, DVD -RW / +RW, DVD-RAM and other recording discs. [0003] The optical disc device continuously records the input audio / video data in the data area (Data Area) of the optical disc. If the recording ends, as figure 1 As shown in , management information for controlling reproduction of recorded data, such as navigation information, is generated and recorded in the file system area (File System Area) located at the front of the above-mentioned data area. [0004] At the same time, if the input audio / video data i...

Problems solved by technology

[0005] However, the problem is that if there is a recording failure (Recording Failure), since the recording operation is forcibly terminated, data will not be input after the recording failure, and it will not be able to be viewed or reproduced.
