Abstract: 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.
