Claims20
A recording medium comprising:
- a substrate made of a material, provided with pads,
- a layer of recording material covering in a discontinuous manner the pads and in a continuous manner the top of the pads, and
- thermal insulation zones located in at least one part of the pads and/or the substrate.
A process for making a recording medium comprising:
- producing pads on a substrate made of a material,
- forming thermal insulation zones in the pads and/or the substrate, and
- forming a layer of recording material, which is discontinuous on the pads and continuous on the top of the pads.
