Abstract:
1. An error recovery method for video recording comprising: obtaining a last writable address of a disk when commencing a defected recording, wherein the disk is a write-once digital versatile disk; searching forward for a file system last written onto the disk from the last writable address; generating a new file system according to the file system and a data segment last written before the commencing of the defected recording; inserting another data segment as a buffer after the data segment; writing the new file system spatially positioned after the buffer of the recorded data segment last written so as to recover the data on the disk; detecting the length of a defective segment on the disk after obtaining the last writable address of the disk; determining whether the length of the defective segment on the disk exceeds a predetermined length or not after searching forward for the file system last written onto the disk; and directly performing a finalization procedure to the disk when the length of the defective segment exceeds the predetermined length.
