Abstract
Multi-channel readback using array heads has been reported in optical recording. A method to reduce both interference along and across the tracks using multi-channel readback is presented. In this method, the non-linear multi-channel decision feedback equalization is used to remove both forms of interference. Simulation results show good improvement (in performance) by using the multi-channel equalization. By this readback method, tracks can be brought closer, thus increasing the areal density. Another advantage of this method is the high data rate possible.
