Abstract

A software detector has been developed to simulate the process of partial-response maximum-likelihood (PRML) detection and to provide great flexibility in the study of the application of PRML to optical data storage. Using this tool, the performance of three linear densities were examined: 0.35 μm/bit without modulation coding, 0.31 μm/bit without modulation coding, and 0.3 μm/bit with the (1, 7) code. The equalized signals exhibit good eye patterns at densities of both 0.35 and 0.31 μm/bit.
