• A threshold adaptation scheme is proposed in a non-Viterbi simple detector for $d=2$ minimum run-length-constraint coded optical recording schemes, to increase robustness to bloom. The detector has a simple structure comprising of a threshold detector, post processing error correction, and decision directed threshold adaptation. The equalization target is a free symmetric 7-tap target and the detection exploits the $d=2$ constraint in the input sequence. The detector is evaluated for digital versatile disk (DVD) specifications and compared with other threshold-based detectors as well as Viterbi detectors following targets of length up to 5. Performance improvement of over 1.5 dB is observed with the proposed feature for bloom larger than 15% of the channel bit period.
