ABSTRACT:
An apparatus for holding digital data. The apparatus includes a medium in which a plurality of dimples are spaced for tracking by a playing apparatus. Each dimple includes a plurality of facets, and each facet represents a data bit. Because the location of each dimple is predetermined, a tracking assembly can use the dimple locations for tracking purposes. Thus there is no need to reserve bits for tracking purposes, and more data can be stored in a given space on a given medium than with previously developed high-density digital storage media.
