Optical data cards for operating sound synthesizer system
First Claim
Patent Images
1. A card for optical reading by a card reader of a card-programmed sound synthesizer system comprising:
- a flat surface having disposed thereon a plurality of parallel tracks of digital information, said tracks comprising optically contrasting marks and spaces and each being disposed a fixed distance from an edge of said card, at least one of said tracks being a timing track formed of uniformly spaced marks and spaces, said marks and spaces representing stored digital signals, said digital signals being formed of a successive plurality of data bytes, each of said data bytes represented on said card in columns orthoganal to said edge, at least one of said data bytes being a stop byte, said columns intersecting each of said plurality of parallel data tracks and corresponding to a timing mark on said timing track, the bits of said data byte, for each said track other than said timing track, determined by whether a mark or space is disposed in said column.

Abstract
An optical data storage and retrieval system uses printed cards having a plurality of parallel tracks of contrasting fields representing digital 1'"'"'s and 0'"'"'s. A timing track is included as one of the parallel tracks. The card is manually read by a plural parallel track reader indexed to an edge of the card. A stop code, start code, checksum and number of data bytes are included in data stored on the cards. The system can sort the data correctly regardless of whether it is read backwards or forwards Error detection is implemented with a checksum system. Data read from the cards are preferably passed to a voice or sound synthesizer which outputs synthesized voice or sounds responsive to the data stored on the cards.
