1. A method for encoding an error correction code (ECC) block, comprising the steps of:

  • (a) generating a user data block having a predetermined size; and

    (b) generating a parity outer code (PO) for a vertical data stream and generating a parity inner code (PI) for a horizontal data stream, in the user data block, wherein the user data block contains at least one column of eraser detection codes (ERDCS) so that erasers can be set or declared for the horizontal data stream at a predetermined interval.
