1-24. (canceled)
A data carrier comprising a ceramic substrate having first and second opposite surfaces and a thickness of at most 500 μm, wherein the first surface of the ceramic substrate comprises a plurality of laser-ablated recesses encoding information, each recess having a depth of at most 1 μm.
A data carrier comprising a ceramic substrate having first and second opposite surfaces and a thickness of at most 500 μm, wherein the first surface of the ceramic substrate is coated with a first coating, the material of the first coating being different from the material of the ceramic substrate, wherein the first coating comprises a plurality of laser-ablated recesses encoding information.
A method of manufacturing a data carrier comprising a ceramic substrate having first and second opposite surfaces and a thickness of at most 500 μm, the method comprising:
- providing the ceramic substrate;
- and
- generating a plurality of recesses in the first surface of the ceramic substrate by laser ablation to encode information, wherein each recess has a depth of at most 1 μm.
A method of manufacturing a data carrier comprising a ceramic substrate having first and second opposite surfaces and a thickness of at most 500 μm, the method comprising:
- providing the ceramic substrate;
- during a coating process, coating either or both surfaces of the ceramic substrate with first and/or second coatings, the material of the first and/or second coatings being different from the material of the ceramic substrate;
- and
- generating a plurality of recesses in the first and/or second coatings by laser ablation to encode information.
A method of reading out information encoded in a data carrier, wherein the data carrier comprises a ceramic substrate having first and second opposite surfaces and a thickness of at most 500 μm, wherein the first surface of the ceramic substrate comprises a plurality of laser-ablated recesses encoding information, each recess having a depth of at most 1 μm, the method comprising:
- illuminating the data carrier with light of a first wavelength;
- detecting light transmitted through the data carrier and/or reflected by the data carrier;
- and
- analyzing the detected light to decode the information encoded in the recesses of the ceramic substrate.
A method of reading out information encoded in a data carrier, wherein the data carrier comprises a ceramic substrate having first and second opposite surfaces and a thickness of at most 500 μm, wherein the first surface of the ceramic substrate is coated with a first coating, the material of the first coating being different from the material of the ceramic substrate, wherein the first coating comprises a plurality of laser-ablated recesses encoding information, the method comprising:
- illuminating the data carrier with light of a first wavelength;
- detecting light transmitted through the data carrier and/or reflected by the data carrier;
- and
- analyzing the detected light to decode the information encoded in the recesses of the first coating.
