摘要：
A method and apparatus for retrieving a single complete copy from multiple stored copies is provided. Information of each of the multiple stored copies is contained in a different set of sectors on disc surfaces in a disc storage system. Each different set of sectors can include at least one defective sector from which information is not recoverable. One copy from the multiple stored copies from which information is recoverable is selected. Defective sectors in the selected copy are identified. Replacement sectors are located from the multiple stored copies other than the selected copy. Information from the selected copy is merged with information from the replacement sectors to form the single complete copy.
