Abstract

Data cards are formed by writing a succession of latent images on a first web of photosensitive film, developing the film and then joining the film with a web of high resolution laser optical recording tape. The webs may be joined in either back-to-back or front-to-back relationship. In the first case there is an eye readable image on one side and formatted optical recording tape on the opposite side. In the second case an eye readable image is optionally adjacent optical recording tape, but on different layers, with both readable from the same side through a transparent substrate or base. The composite web is cut transversely to its lengthwise dimension into a plurality of wallet size members. Bar code is recorded together with the latent image so that in checking cards for quality control purposes, defective cards may be correlated with particular images in order that a defective card be recreated. The high resolution optical recording tape is preformatted with continuous servo tracks or data location grids without header information so that registration of the eye readable images and the laser recording tape is not necessary.

Claims

1. A method of forming a wallet size data card comprising:

reproducing a plurality of visible images on a first web from a roll, said first web having a front side, a back side and a width dimension not exceeding the width dimension of a wallet size card, the length of the visible image not exceeding the length dimension of a wallet size card,

forming a second web from a roll of high resolution laser optical recording tape containing servo tracks or data location grids, said second web having a front side, a back side and a width dimension,

joining the first web to the second web wherein one side of the first web is proximate to a corresponding side of the second web, and

cutting the joined web at intervals along the lengthwise dimension thereof into a plurality of wallet size cards, each card having a visible image and optical recording tape.

2. The method of claim 1 wherein the backside of the first web is joined proximate to the backside of the second web whereby said joined webs are read from opposite sides.

3. The method of claim 1 wherein the front side of one web is proximate to the back side of the other web with visible images and data laterally optically adjacent wherein optical images and optical data are read from the same side of the card.

4. The method of claim 2 further defined by producing visible images on said first web by means of laser scanning of photographic emulsion with picture information thereby producing latent images and then developing said latent images prior to joining the first web to the second web.

5. The method of claim 4 further defined by writing bar code latent image indicia onto said emulsion at the time said picture latent images are formed with said laser.

6. The method of claim 5 further defined by scanning the optical recording tape of each card for defects and correlating a defective card with said bar code indicia.

7. The method of claim 6 further defined by repeating the reproducing of a visible image on another web corresponding to the visible image of a defective card and joining the visible image web to a portion of optical recording tape in a relation similar to said defective card thereby forming a new card.

8. A method of forming a wallet size data card comprising,

writing a succession of latent images containing picture information with a scanning laser onto a first elongated web of photosensitive film, said first web having a front side and a back side,

advancing said web and developing said latent images into a succession of eye readable pictures,

joining a second elongated web of high resolution laser optical recording tape with said first web, the second web having a front side and a back side, the two webs joined with one side of the first web proximate to a corresponding side of a second web, thereby forming a composite web,

cutting the composite web transversely into lengths forming wallet size cards, each card having an eye readable picture portion and an optical recording tape portion.

9. The method of claim 8 wherein the backside of the first web is joined proximate to the backside of the second web whereby said joined webs are read from opposite sides.

10. The method of claim 8 wherein the front side of the first web is proximate to the front side of the second web with visible images laterally adjacent laser optical recording material wherein optical images and optical data are read from the same side of the card.

11. The method of claim 8 further defined by producing visible images on said first web by means of laser scanning of photographic emulsion with picture information thereby producing latent images and then developing said latent images prior to joining the first web to the second web.

12. The method of claim 8 further defined by writing bar code latent image indicia onto said emulsion at the time said picture latent images are formed with said laser.

13. The method of claim 12 further defined by scanning the optical recording tape of each card for defects and correlating a defective card with said bar code indicia.

14. A data card comprising,

a card substrate having front and back opposed major surfaces and a length and width comparable to wallet size bank cards,

a high resolution DRAW optical recording material applied to a first surface portion of the card,

a recording medium carrying a visible image applied to a second surface portion of the card, and

a low resolution machine readable scanner coding strip applied to a third surface portion.

15. The data card of claim 14 wherein said optical recording material and said visible image face on the same side of the card.

16. The data card of claim 14 wherein said optical recording material and said visible image face on opposite sides of the card.

17. The data card of claim 14 wherein said scanner coding strip comprises a bar code strip.
