Background

With the continuous development of streaming media technology, how to record streaming media files on an optical disc for multiple times becomes an urgent problem to be solved.

For a write-once optical disc, a conventional optical disc recording method is to pack a file to be recorded first to generate a mirror image file, that is, to generate a mirror image file in a UDF (Universal disk format) format from a file in a hard disk according to a standard of a UDF file system, to record the mirror image file in the hard disk or a memory, and then to sequentially read the mirror image file from the hard disk or the memory and record the mirror image file in the optical disc.

The conventional recording method requires that the buffered file is written into the optical disc once when recording is started. That is, after the available capacity of an optical disc is reached, the files and the metadata are written into the optical disc until all the files and the metadata are written into the optical disc, which results in untimely recording of the files, and when the recording of the files fails, the whole optical disc is invalidated, and the recorded content of the optical disc is also invalidated, thereby resulting in the loss of the content of the files.
