densityinform
Densityinform is a theoretical metric used in information science and materials physics to quantify the amount of information content contained within a given physical volume. It is defined as the information content I carried by a medium divided by its physical volume V, yielding densityinform = I/V, with units such as bits per cubic meter. The concept integrates both encoding efficiency and physical packing constraints of the medium.
The information content I can be modeled in different ways. In practice, I is often taken as
Densityinform is used to discuss theoretical storage density limits across technologies such as magnetic, optical, holographic,
Limitations include dependence on arbitrary definitions of what counts as information and how it is encoded,
