Abstract
A storage device comprises a substrate having a recording layer, the recording layer having plural regions associated with respective plural storage cells. A light source generates write light having a first wavelength to write to the storage cells, wherein the storage cells have a size less than the first wavelength.
Claims29
A storage device comprising:
- a substrate having a recording layer, the recording layer having plural regions associated with respective plural storage cells;
- and
- a light source to generate write light having a first wavelength to write to the storage cells, wherein the storage cells have a size less than the first wavelength.
A storage device comprising:
- a support structure;
- a recording layer formed over the support structure;
- a write mechanism to write to storage cells in the recording layer by selectively forming, using laser light having a wavelength, amorphous regions and crystalline regions in respective storage cells, the write mechanism to write to the storage cells each having a size smaller than the wavelength of the laser light;
- and
- a read circuit to detect electrical signaling in the amorphous and crystalline regions to read states of the storage cells.

A method of storing data in a storage device, comprising:
- generating, with a laser source, a laser light targeted at a storage cell of the storage device, the storage cell including a region of a phase-change layer;
- and
- programming the region in the storage cell to one of a first phase and a second phase,
- wherein the laser light produced by the laser source enables programming of the region in the storage cell that has a size smaller than a wavelength of the laser light.
