Data can be transmitted and represented by signal gaps in a transmission, the gaps having various attributes. In various examples, data points are encoded and represented by the attributes of said signal gaps. Various attributes of such gaps, including duration, pattern, quantity, time, and/or coordination with a gap in another signal can represent data.

An apparatus includes a first storage cell with an electrical property. The first storage cell is configured to change the electrical property in response to a first light energy, and to maintain the change to the electrical property. The first storage cell is also configured to alter the change to the electrical property in response to a second light energy, and to maintain the alteration to the change to the electrical property. A second storage cell disposed over the first storage cell in a vertical plane of the first storage cell. A third storage cell disposed adjacent to the first storage cell in a horizontal plane of the first storage cell.

Data can be encoded in physical medium and represented by shapes having many various physical attributes. In various examples, data points are encoded and represented by the physical shape, color, size, and/or structure of objects. In one embodiment, holes in memory surface substrates represent data. Various attributes of such holes, including depth, profile size, profile shape, and/or angle can represent data.

A method of detecting the positions of a plurality of probes. An input beam is directed into an optical device and transformed into a plurality of output beamlets which are not parallel with each other. Each output beamlet is split into a sensing beamlet and an associated reference beamlet. Each of the sensing beamlets is directed onto an associated one of the probes with an objective lens to generate a reflected beamlet which is combined with its associated reference beamlet to generate an interferogram. Each interferogram is measured to determine the position of an associated one of the probes. A similar method is used to actuate a plurality of probes. A scanning motion is generated between the probes and the sample. An input beam is directed into an optical device and transformed into a plurality of actuation beamlets which are not parallel with each other.

The present invention is in the field of an atomic scale data storage device which uses vacancy manipulation, a method of providing said device, and a method of operating said device. Prior art mass data storage devices typically rely on magnetic materials forming discrete arrays or on nanoscale transistors. Further examples are e.g. optical systems such as a DVD and a compact disk. These devices and systems have a large, but for some applications still limited, storage capacity.
