Abstract
Abstract The systems of this invention involve the storage of information on a record medium in the form of patterns of spots arrayed along one or more tracks, the patterns are spaced apart a distance which is a fraction of the length of the pattern so that there is partial overlap of the patterns along the track. The patterns may be uniformly or non-uniformly spaced spots, and the patterns can be sequentially the same or different patterns. All of the spots in the patterns have the same character, and are presented to a reading means sequentially. The spacing of patterns along the track may be uniform or variable. Each pattern may represent a single bit, or a single character.

Total Claims: 28
Claim 1
Independent Claim
235 words
An information system comprising; a. a record medium; b. at least one track containing aplurality of recordings along said medium, each of said recordings comprising a unique pattern of spaced spots arranged longitudinally along said track, each pattern being of longitudinal dimension D along said track, each of said patterns corresponding to and uniquely indicative of a discrete unit of information, all spots in said patterns being of the same character, and applied successively to a reading means; c. reading means for reading said patterns of spots in said track, said reading means comprising means to compress and detect said patterns and to convert said patterns to singlevalued point signals representative of said discrete units of information, said means capable of reading each of said signals independently of each of the other signals; d. the minimum longitudinal spacing of the separate patterns of said plurality of patterns along said track being d, where d is the minimum distance of traverse of said track past said reading means to read a single pattern, and is less than D, so that successive patterns partially overlap each other along said track, said dimension D Kd, where K is a quantity greater than 1; and e. means to relatively move said record medium and said reading means in the direction along said track, such that a peak signal value for any given pattern occurs in only one relative position.
