A data writing and reading method is applied to a data storage system. The storage system includes a processor, a charged particle beam excitation modulation component, and a recording medium. The method is performed by the processor. The data writing method includes obtaining to-be-written data; controlling, based on the to-be-written data, the charged particle beam excitation modulation component to generate a charged particle beam array with a target modulation feature; and controlling the charged particle beams in the charged particle beam array to act on the recording medium to generate, in a target area of the recording medium, a target recording feature corresponding to the to-be-written data.

There is presented a method for geometrically modifying plasmonic structures on a support structure, such as for printing or recording, said method comprising changing a geometry specifically of plasmonic structures, wherein said changing the geometry is carried out by photothermally melting at least a portion of each of the plasmonic structures within the second plurality of plasmonic structures by irradiating, the plasmonic structures with incident electromagnetic radiation having an incident intensity in a plane of the second plurality of plasmonic structures, wherein said incident intensity is less than an incident intensity required to melt a film of a corresponding material and a corresponding thickness as the plasmonic structures within the second plurality of plasmonic structures.
