Abstract
A phototypesetter font disk has a plurality of circumferentially spaced, optically readable indicia and a strobe track radially spaced from the indicia which contains a plurality of circumferentially spaced timing marks. Each indicia has an associated timing mark that is both radially and circumferentially spaced from its respective indicia. The strobe track has an identifiable reference location from which each indicia timing mark is angularly spaced. Additional marks are interposed between the indicia timing marks on the strobe track to define digital data relating to the font disk. Typically, such data includes font identification information.
