Abstract

Two-dimensional modulation codes were recently introduced as a method to increase data storage densities. These codes are a generalization of the usual run-length-limited (d, k) codes and provide for increased storage density by relaxing the k-constraint and encoding multiple tracks in parallel. The use of these codes requires that timing information be derived from multiple tracks read in parallel. This paper introduces a timing recovery circuit for use by systems that employ two dimensional modulation codes. The circuit generalizes the familiar square-and-filter approach. Computer simulations are used to determine the performance of this circuit in terms of peak-to-peak jitter vs. signal to noise ratio at various pulse densities. Another circuit introduced in this paper is used to remove relative time-shift from adjacent tracks. This circuit is necessary for proper operation of the timing recovery circuit in systems with removable media.
