Abstract
Abstract Data are recorded on an information carrier having at least one system of parallel lines thereon, subdivided into three groups, preferably constituting two outer groups of two lines and an inner group of five lines. The spacing between adjacent groups of lines is different from the spacing between adjacent lines in one group. Dots and dashes are applied at a constant angle to, and in progression along the length of, the lines, and have a prearranged information content by being placed at selected transverse positions.

Claim 1
Independent Claim
142 words
A method of recording data using an information carrier having at least one system of lines arranged in parallel relationship thereon, said at least one system of lines being formed by three associated groups of lines, the perpendicular distance between adjacent ones of said three groups of lines being different from the perpendicular distance between adjacent ones of the lines within each said group, comprising the step of manually recording symbols Progressively longitudinally of said lines, each symbol being made up of at least one notation mark selected from the group consisting of a set comprising combinations of dots and dashes, and a set comprising dashes, at least some of which intersect at least two of said lines, and being applied within the confines of the system of lines to extend in a direction making a substantially constant angle with said lines.
