ABSTRACT:
Embodiments are directed to recording digital data on an optically ablatable digital storage media. In one embodiment, a device configured to ablate portions of ablatable material on an optically ablatable digital storage media receives digital data that is to be recorded on a recording layer of an optically ablatable digital storage media. The recording layer is formed on a substrate with zero or more intervening layers between the recording layer and the substrate. The recording layer includes ablatable material capable of storing digital data. The device ablates the ablatable material in the recording layer according to a sequence defined by the received digital data such that the ablated portions correspond to data points of the received digital data.
