ABSTRACT:
The record indexing system includes a substrate sheet with a plurality of removable labels adhered on one surface of that sheet. The labels are substantially uniform in size and each extends along an associated longitudinal axis. Each label includes three zones on its top surface. The first zone extends from one end of the label along its longitudinal axis, the second zone extends from the other end of the label along that axis and the third zone separates the first and second zones and has a predetermined length in the direction of the axis. The first and second zones are characterized by one optical absorption spectrum and the third zone is characterized by another optical absorption spectrum. The separator zones for the labels are offset from one end of the labels by a different distance for each label.
