System and method for making recordable wallet-size optical card

Claim 1

A method of making an optical data card comprising, prerecording information on a strip of immediate read laser recording material, adhering said strip to a wallet-size card base, said strip being laser recordable in place on said card, bonding a protective transparent laminating material to the recording surface of said strip, recording information on said strip with a laser through the laminating material and reading said information of said strip with said laser as said information is written.

Claim 2

A method of making an optical data card comprising, prerecording information on a strip of immediate read laser recording material, adhering said strip to a wallet-size card base, said strip being laser recordable in place on said card, bonding a protective transparent laminating material to the recording surface of said strip, recording information on said strip with a laser through the laminating material and reading said information of said strip with said laser as said information is written.

Claim 3

A method of making an optical data card for information storage and recording comprising, photolithographically prerecordiing information on a strip of high resolution, immediate read, direct-read-after-write laser recording material, adhering said strip to one side of a wallet-size plastic card base, said strip being laser recordable in place on said card, bonding a protective transparent plastic laminating material to the recording surface of said strip, recording information on said strip with a laser through the laminating material and reading said information on said strip as said information is written.

Claim 4

A method of making an optical data card for information storage and recording comprising, photolithographically prerecordiing information on a strip of high resolution, immediate read, direct-read-after-write laser recording material, adhering said strip to one side of a wallet-size plastic card base, said strip being laser recordable in place on said card, bonding a protective transparent plastic laminating material to the recording surface of said strip, recording information on said strip with a laser through the laminating material and reading said information on said strip as said information is written.

Claim 5

A system for sequentially recording transaction data by means of a laser comprising, a wallet size card with a transparent plastic laminating material protectively bonded to a strip of high resolution optically reflective immediate read laser recording material adhered to one side of the card, being laser recordable in place on said card and having a minimal laser recording capacity of 250,000 binary bits, having laser created data spots in a surrounding optically contrasting field of said strip, representing accumulated transaction data, with a dimension of said spots being less than 25 microns, the optical reflective contrast ratio of said spots with respect to the surrounding field being a least two to one, laser means having a beam disposed in laser writing relation with respect to said strip for writing said spots, representing transaction data, the spots having a size of less than 25 microns, a light detector means disposed in reading relation with respect to said strip and said beam for immediately reading said spots upon writing, and means for providing relative motion between the laser beam and the card for sequentially reading transaction data on the card and writing transaction data onto said card in a permanent manner.

Claim 6

A system for sequentially recording transaction data by means of a laser comprising, a wallet size card with a transparent plastic laminating material protectively bonded to a strip of high resolution optically reflective immediate read laser recording material adhered to one side of the card, being laser recordable in place on said card and having a minimal laser recording capacity of 250,000 binary bits, having laser created data spots in a surrounding optically contrasting field of said strip, representing accumulated transaction data, with a dimension of said spots being less than 25 microns, the optical reflective contrast ratio of said spots with respect to the surrounding field being a least two to one, laser means having a beam disposed in laser writing relation with respect to said strip for writing said spots, representing transaction data, the spots having a size of less than 25 microns, a light detector means disposed in reading relation with respect to said strip and said beam for immediately reading said spots upon writing, and means for providing relative motion between the laser beam and the card for sequentially reading transaction data on the card and writing transaction data onto said card in a permanent manner.
