Abstract:
1. A DVD disc having data sectors according to DVD standard, the DVD disc comprising: a first data sector recorded in an error correction code (ECC) block, the first data sector having a first error pattern configured in such a way that one of 0x85, 0x8E, 0x95, 0x9E, 0xA4, 0xA6, 0xA8, 0xA9, 0xAB, 0xAD, 0xAE, 0xAF, 0xB3, 0xB4, 0xB5, 0xB8, 0xBA, 0xBC, 0xBE, 0xC0, 0xC2, 0xC4, 0xC7, 0xC8, 0xCB, 0xCD, 0xD3, 0xD5, 0xD9, 0xDF, 0xE2, 0xE5, 0xE7, 0xED, 0xEE, 0xF0, 0xF2, 0xF4, 0xF6, 0xF8, 0xFA, and 0xFC is repeated in a main data field of the first data sector; and a second data sector recorded in the error correction code (ECC) block, the second data sector having a second error pattern configured in such a way that one of 0x85, 0x8E, 0x95, 0x9E, 0xA4, 0xA6, 0xA8, 0xA9, 0xAB, 0xAD, 0xAE, 0xAF, 0xB3, 0xB4, 0xB5, 0xB8, 0xBA, 0xBC, 0xBE, 0xC0, 0xC2, 0xC4, 0xC7, 0xC8, 0xCB, 0xCD, 0xD3, 0xD5, 0xD9, 0xDF, 0xE2, 0xE5, 0xE7, 0xED, 0xEE, 0xF0, 0xF2, 0xF4, 0xF6, 0xF8, 0xFA, and 0xFC is repeated in a main data field of the second data sector, wherein the first and second error patterns cause reading error during a descrambling process of the main data field of the first data sector and the main data field of the second data sector, wherein, the first data sector and the second data sector are consecutively recorded in the error correction code (ECC) block.
