Problems solved by technology
[0007] Next, the present invention is proposed in order to solve the above-mentioned problems. The purpose of the present invention is to provide an optical disc defect correction device and method that can be recorded once. While recording the file system, navigation information, and RSAT, the recording position (RSAT-Add) information of the above-mentioned RSAT is stored on the memory in the device, and then it cannot be If the spare space allocation table is detected normally, the recording position information of the spare space allocation table stored in the above-mentioned memory can be referred to, and since the spare space allocation table recorded on the optical disc can be retrieved and detected, even if a disc defect occurs, It can also read and play recorded audio and video data normally

Embodiment Construction
[0022] Embodiments of the recordable optical disc defect correction device and method of the present invention will be described in detail below with reference to the accompanying drawings.
[0023] First of all, the defect correction device and method for a recordable optical disc of the present invention can be applied to various types of optical disc machines that are the same as digital video disc recorders, for example, on the above-mentioned digital video disc recorder, its The configuration includes an optical disc 10, an optical pickup 11, a video disc recording (VDR: Video Disc Record) system 12, a microcomputer 13, an operating system display (OSD) generating unit 14, an information generating unit 15, and a memory 16.
[0024] On the one hand, if the above-mentioned optical disc 10 in the above-mentioned information generation unit 15 as shown in FIG. Allocation table (RSAT) information generates the above-mentioned information, and in the above-mentioned microcompu...

The invention relates to a defect augmenting device and method of disc which can be recorded for one time, for example, digital video disc recorder records data in disc which is same as digital video disc, if the data recording ends, the file system, navigation information and recording superfluous space distributed table are recorded, at the same time, the recording position information of said superfluous space distributed table is stored in nonvolatile memory which is same as flash memory, after that, if the superfluous space distributed table can not be detected regularly resulted by defect of disc, the recording position information of said superfluous space distributed table is stored in nonvolatile memory can be referred to, the superfluous space distributed table recorded in said disc can be searched, so the problem that recorded audio and video data can not be played for the defect of disc, so it is a useful invention.
Description
technical field [0001] The present invention relates to a device and method for correcting disc defects that can be recorded once, in particular to a digital video disc (DVD+R) that can be recorded once. An apparatus and method for correcting a recordable disc defect of audio and video data recorded on an optical disc. Background technique [0002] General optical discs that can record and play high-quality video data and high-quality audio data, such as digital video discs (DVD: Digital Versatile Disc), are widely used. The above-mentioned digital video discs include playback-specific digital video discs. (DVD-ROM), digital video discs that can be recorded once (DVD-R, DVD+R), and digital video discs that can be recorded again (DVD-RW, DVD+RW, DVD-RAM). [0003] On the one hand, when a DVD-Recorder that records data on a DVD-Recorder as described above or can play it, for example, inserts and installs a DVD+R in the device, and operates the data recording operation, as sho...
