We discuss a novel two-dimensional parallel technique for reliable data detection in page-oriented optical memories. The method is motivated by decision feedback techniques and is fully parallel, offering convenient, locally connected electronic implementation. The algorithm is shown to offer significant improvements over simple threshold detection and in some cases can approach the maximum-likelihood bound of data reliability.
