An efficient decoding strategy of 2D-ECC for optical recording systems


Two-dimensional error correction codes (2DECCs) have been the cornerstone of all three generations of optical recording CD, DVD and BD. Research into powerful error correction methods is paramount for the development of high-capacity optical recording systems. A Reed-Solomon product-code (RS-PC) for DVD systems performs error and erasure decoding by giving and taking erasure information between two ECCs. In this paper, we will present a new error correction method that performs erasure decoding using the only erasure information supplied from a modulation code decoder – more specifically, the EFMPlus code for DVD systems. We will evaluate the decoding efficiency of the new error correction method under a channel environment with various error types.
