Abstract of the Disclosure An optical recording medium in tape form which may either be strips of tape or reels of tape, all having preformatted continuous servo tracks from one end to the other. Preformatted servo tracks are spaced-apart lines, so as to permit data spots to be written between or on the tracks. The tracks may extend either longitudinally, parallel to the lengthwise direction of the tape or in a perpendicular direction, extending in directions trans- verse to the length of the tape, or in a grid-like pat- tern. The tape web may be joined to a web of transparent protective material over the surface of the strip. A data card may be made using a strip of such tape without regard to registration of the tape with markings on the card. Tracks may be made by directly writing with a laser on direct-read-after-write laser recording material or by photolithography or by embossing.
