Abstract
Abstract A data card having a pair of spaced apart information records. One record is a strip of high resolution reflective laser recording material, such as a metallic film. The other strip is a magnetic recording material. The strip of laser recording material has a capacity for recording at least 250,000 bits represented by pits having a dimension less than 50 microns.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
73 words
A data card for use with a card reader-writer comprising, a wallet size card having opposed sides and a length equal to or exceeding a width, a first strip of high resolution reflective direct-read-after-write laser recording material adhered to the card, the reflectivity of said first strip greater than 15%, said first strip being laser recordable in place on said card, and a second strip of magnetic recording material adhered to the card.
Claim 2
Dependent Claim
73 words
A data card for use with a card reader-writer comprising, a wallet size card having opposed sides and a length equal to or exceeding a width, a first strip of high resolution reflective direct-read-after-write laser recording material adhered to the card, the reflectivity of said first strip greater than 15%, said first strip being laser recordable in place on said card, and a second strip of magnetic recording material adhered to the card.
Claim 3
Dependent Claim
20 words
The card of claim 1 wherein said first and second strips are adhered to the same side of said card.
Claim 4
Dependent Claim
19 words
The card of claim 1 wherein said first and second strips are adhered to opposite sides of said card.
Claim 5
Dependent Claim
34 words
The card of claim 1 wherein said first and second strips are disposed parallel to each other and spaced apart on the same side of said card, said strips extending in the lengthwise direction.
