A defect detecting apparatus and a defect detecting method performs highly efficient and reliable defect detection over an optical disk. According to the defect detecting method, defect information is obtained during data recording. The necessity of data verification and the range of verification-demanding area are determined according to the defect information. The defect address is found efficiently by performing a data verification procedure over the verification-demanding area. The defect detecting method according to the present invention conducts data verification on defect-prone addresses instead performing a global examination for address areas recorded with data. Thereby, the defect detecting efficiency is enhanced.
