Data tape and coding and decoding method of printed data

摘要

The invention relates to a data strip for storing coded data having a high density. The printed surface of the data strip is divided up into cells and one of at least two different patterns (1, 2) having a characteristic, predefined form is respectively printed in a two dimensional cell having a predefined form. The invention also relates to a method for coding and decoding data on printed supports. Coding occurs in the form of two dimensional cells and cells are positioned at specific points on the support, respectively containing at two different patterns having a characteristic and predefined form and the inner structure of the cells is used for decoding.
