Abstract
The present invention relates to a data storage device comprising: a polymer layer for storing data in the form of topographic features; a substrate comprising a conductor, a first surface of the polymer layer being provided on the substrate; and at least one probe which, when the device is in use, interacts with a second surface of the polymer layer, wherein, when in use, the data storage device is operable to apply a first electrical potential to the at least one probe relative to the substrate, thereby to cause a protrusion to be formed on the second surface of the polymer layer.
Claims22
A data storage device comprising:
- (1) a polymer layer for storing data in the form of topographic features;
- a substrate comprising a conductor, a first surface of the polymer layer being provided on the substrate;
- and
- (2) at least one probe which, when the device is in use, interacts with a second surface of the polymer layer, wherein, when in use, the data storage device is operable to apply a first electrical potential to the at least one probe relative to the substrate, thereby to cause a protrusion to be formed on the second surface of the polymer layer.
A method for producing a data storage device, the data storage device comprising a polymer layer, a first surface of which is provided on a substrate comprising a conductor, the method comprising the steps of:
- (1) interacting at least one probe with a second surface of the polymer layer and
- (2) applying a first electrical potential to the at least one probe relative to the substrate, thereby to cause a protrusion to be formed on the second surface of the polymer layer.
