Blank disk record error compensating method in compact disk recording apparatus

Abstract

The invention relates to blank disc record error compensating method; the invention includes steps as following: the first step, the incompetent area is checked and saved by detecting blank medium; the second step, during the recording, the recording speed of said incompetent area is decreased. By the invention, the incompetent area of blank disc (blank medium) can be induced in advance, said incompetent area can be recorded by the lowest speed to reduce the problem generated during the recording and playing furthest.

Description

technical field [0001] The present invention relates to a blank disk recording error compensation method in an optical disk recording device, in particular to a blank disk recording error compensation method capable of reducing unqualified media recording errors and ensuring stable recording quality. Background technique [0002] Among the various CD and DVD R and +R series media currently on the market, there are often discs that show unqualified phenomena in specific areas. Some of these unqualified media are unrecognizable to the naked eye due to misapplied dyes or poor media wobble (Wobble) effects. [0003] When abnormal conditions occur in the process of using the above-mentioned unqualified media that cannot be confirmed by the naked eye, ordinary (lack of technical awareness) consumers often mistakenly believe that there is a problem with the optical drive, which will bring great loss to the image of the optical drive manufacturing company. . [0004] At present, i...

Problems solved by technology

After recording in this part, the non-ideal waveform of the same period will also remain in the RF signal, so playback errors are very likely to occur

[0022] In addition, if there are fingerprints left on the disc, as shown in Figure 3, in the area where the fingerprints are left, there will be a large-scale phenomenon that the RF signal becomes irregularly larger
