Abstract: This thesis is dedicated to the design and analysis of parity-check (PC)-code-based optical recording systems to achieve higher recording capacity with low implementation complexity, for high-density blue-laser disc systems. The main contributions include six parts. The first part proposes a generalized Braat-Hopkins model for optical recording channels. The second part investigates the performance bounds for bit error rates and error event probabilities, different PC codes, as well as simple and efficient post-processors. The third part derives analytically the relationship between the number of encoder states and the maximum size of certain capacity-approaching constrained codes, and obtains the minimum number of encoder states. The fourth part proposes a general and systematic code design technique for constructing capacity-approaching constrained PC codes. The fifth part proposes novel detection, PC coding and post-processing schemes to combat media noise. The sixth part analyzes the failure rates of error correction codes for the developed PC-code-based systems.
