Abstract
The present invention relates to a method of high-speed recording and reading data on or in a layer (10) of a first material and to a device for high-speed recording and reading data on or in a layer (10) of a first material using a laser source (19, a galvanometer (4) and a digital micromirror (5) adapted to emit multiple laser beams.
Claims21
A method for high-speed recording data on or in a layer of a first material, the method comprising:
- providing a layer of the first material;
- and
- selectively illuminating a plurality of regions of the layer of the first material with laser light in order to selectively manipulate material at the plurality of regions of the layer of the first material;
- wherein the plurality of regions of the layer of the first material are selectively illuminated by means of a combination of a galvanometer scanner and a digital micromirror device.

A device for high-speed recording data on or in a substrate, the device comprising:
- a laser source adapted to emit laser light;
- a galvanometer scanner adapted to pass the laser light;
- a digital micromirror device adapted to emit multiple laser beams formed from the passed laser light;
- a substrate holder for mounting the substrate;
- and
- focusing optics adapted for focusing each of the multiple laser beams emitted by the digital mirror device onto the substrate mounted on the substrate holder, wherein the multiple laser beams are adapted to encode recorded data on the substrate;
- wherein the galvanometer scanner is adapted to temporally distribute the laser light over the digital micromirror device.
