Document Type and Number:

WIPO Patent Application WO/2004/047085

Kind Code:

A1

Abstract:

There is provided a method for encoding a random bit stream in two-dimensions for storage on a storage medium. The random bit stream is encoded (3310) using Variable Aperture Coding (VAC) so as to generate a constant amplitude, varying pulse-width, VAC encoding that represents the random bit stream by a plurality of pulses separated using only transition widths included in a pre-specified set of transition widths.
