Paper Abstract

Tilt is a major source of distortion for the DVD channel. This paper is aimed at understanding the effect of tilt on the readback signal. Equalized signals were collected from DVD-ROM media on an optical spin stand with a variable tilt stage. A simulated version of duty cycle correction (DCC) was applied to each signal to cancel the baseline drift. The pulse response, which characterizes the signal under the linear superposition assumption, was extracted for each signal. The pulse response of the DVD-ROM channel is shown to be highly affected by tangential tilt while the effect of radial tilt is minimal.
