  • Method for generating read error during standard DVD disc manufacturing
    Patent number: 8201265
    Abstract: A method is disclosed for generating a read error during standard DVD disc manufacturing. The method generates a read error in an error correction code (ECC) block including a specific error generation data pattern, when main data of 2,048 bytes is generated using the specific error generation data pattern according to a DVD standard. The error-pattern original data is inserted into the main data that is scrambling based on a DVD standard. The scrambled data is recorded in data sectors. The scrambled data including an error pattern which causes a read error is consecutively recorded in the data sectors included in the ECC blocks, in a process in which the data sectors are grouped based on 16 units to form the ECC blocks.
