Abstract

Machine processable record cards having punched or mark sensing indicia include a photographic film transparency and magnetic indicia to permit data processing machine selection of records containing an audio-visual message. In A, record card 1 of conventional card stock has abraded shoulder 2 surrounding rectangular aperture 3. Film chip 4 is adhered by pressure-sensitive or thermoplastic adhesive to shoulder 2 so as completely to cover aperture 3. Card 1, however, has another abraded shoulder 5 surrounding a different rectangular aperture 6. Magnetic film chip 7 is suitably bonded to 5 overlying 6. For ease of manufacture, shoulders 2 and 5 and apertures 3 and 6 are preferably of identical size and identically dimensioned from both long edges and from the nearest short edge.

Record Cards With Magnetic and Visual Data

Machine processable record cards having punched or mark sensing indicia include a photographic film transparency and magnetic indicia to permit data processing machine selection of records containing an audio-visual message. In A, record card 1 of conventional card stock has abraded shoulder 2 surrounding rectangular aperture 3. Film chip 4 is adhered by pressure-sensitive or thermoplastic adhesive to shoulder 2 so as completely to cover aperture 3. Card 1, however, has another abraded shoulder 5 surrounding a different rectangular aperture 6. Magnetic film chip 7 is suitably bonded to 5 overlying 6. For ease of manufacture, shoulders 2 and 5 and apertures 3 and 6 are preferably of identical size and identically dimensioned from both long edges and from the nearest short edge. This enables the apertures to be formed by passing a card twice through conventional abrading and scoring apparatus. If the cards remain face up but are turned 180 degrees, shoulders 2 and 5 are abraded in the same side of the card as shown.

If the cards are turned upside down after the first pass, shoulders 2 and 5 are abraded in opposite sides of the card.

Magnetic indicia can be recorded on chip 7 before or after its insertion in the card and modified or supplemented after insertion in the card. The card can contain an illustrated lecture or status report on a selected subject, with an audio explanation from magnetic chip 7 of data displayed vis...
