摘要

PROBLEM TO BE SOLVED: To perform defect management by determining whether a defect is a permanent defect or not.SOLUTION: An optical disc defect registering method according to the present invention includes the steps of: (A) detecting a defect from an optical disc and determining the attribute or type of the defect detected; and (B) recording defect attribute information, by which it can be determined whether the defect is a permanent defect including a bubble present inside the optical disc or a non-permanent defect including a fingerprint or dust present on the surface of the optical disc, along with defect location information indicating the location of the defect, on the optical disc.
