Apparatus and method for increasing storage capacity of recording media
 An improved method of configuring digital information in a recording storage media so as to significantly increase the information storage capacity of the media, and the media containing such configured digital information are disclosed. Information containing markers are arranged and configured along tracks in the media in a manner such that markers of adjacent tracks are offset relative to one another. Inter-track spacings of arcuately shaped tracks on a storage media are progressively reduced as a function of the radial spacing of the tracks from their center of curvature, further increasing the marker packing density. Return to zero pulsed modulation schemes are employed to maximize the amount of information recorded in a given number of marker locations. Drive means for reading digital information configured on storage media according to the principles of this invention are provided.
