Abstract
A data storage medium having a pattern representing data bits arranged in a plurality of interlocked triangularly shaped tracks. The medium may be a prerecorded optical storage material having a set of optically contrasting marks arranged in the tracks. The track width increases from a start point to an end point at a constant rate that depends on the maximum allowable angle of skew. The medium, which can be prerecorded with the pattern using exposure to actinic radiation through a like-patterned master, can have either a card, tape or drum format.
