ABSTRACT:
A set of high density codes for optical recording of binary data. The data bits of each set are encoded into a block code having a plurality of symbols, each symbol having a plurality of symbol position with an even number of holes with the constraint that there be at least two symbol positions between holes or groups of holes. Additionally, a least one hole is never recorded at a predetermined boundary symbol position. This "empty" symbol position permits symbol position dimensions to be reduced while maintaining good read margins to provide high density recording.
