A recording medium includes a recording layer. The recording layer includes an aliphatic polymer, and a multiphoton absorption compound containing at least one bond selected from the group consisting of a carbon-carbon double bond, a carbon-nitrogen double bond, and a carbon-carbon triple bond, and having a multiphoton absorption characteristic. When the thickness of the recording layer is 100 ?m, the transmittance of the recording layer in the thickness direction with respect to light having a wavelength of 405 nm is greater than or equal to 80%.

The present disclosure provides systems and methods associated with data storage using atomic films, such as graphene, boron nitride, or silicene. A platter assembly may include at least one platter that has one or more substantially planar surfaces. One or more layers of a monolayer atomic film, such as graphene, may be positioned on a planar surface. Data may be stored on the atomic film using one or more vacancies, dopants, defects, and/or functionalized groups (presence or lack thereof) to represent one of a plurality of states in a multi-state data representation model, such as a binary, a ternary, or another base N data storage model. A read module may detect the vacancies, dopants, and/or functionalized groups (or a topographical feature resulting therefrom) to read the data stored on the atomic film.
