The scratch determination unit determines that predetermined sectors are affected by a single continuous scratch if the predetermined sectors are defective and a distance therebetween is not larger than the length of a single continuous scratch. The alleged defect setting unit sets sectors between the predetermined sectors and around each of the predetermined sectors as alleged defective sectors if the defective sectors are determined to be affected by the single continuous scratch.
