Paper Abstract

The conventional inspection methods for the write-once optical disk are consist of visual method with non-destructive and recording/playback of the sampled disks with destructive. So the quality can not be assured when arrived at the customer due to lack of quality inspection. We find the new method consist of recording/playback for each disk manufactured. The recording/playback is performed at the edge area of the disk where tracks are extended. This area is not conflict with the standard and the disk can be used as a virgin disk at the customer. From the experiment, we find that the ratio of bad disks can be reduced to 0.5% from 7% with proposed method.
