摘要:
The invention is directed to a method for reading information from an optical data storage medium, operating by: obtaining at least one coding/decoding unit of the optical data storage medium wherein the coding/decoding unit comprises a plurality of codewords; checking if the coding/decoding unit is reliable; and when the coding/decoding unit is not reliable; selecting at least one spec-defined codeword from the plurality of codewords. The spec-defined codeword includes a plurality of spec-defined fields defined by the specification of the coding/decoding unit; checking whether the spec-defined codeword is reliable; and when the spec-defined codeword is reliable, retrieving information from the spec-defined codeword.
