In the holographic data storage, by recording the volume hologram on the medium, it is possible to superimpose and record different data on one place and reproduce it.
However, since noise at the time of data reproduction affects reproducibility of information, electromagnetic field analysis for noise evaluation is required.
In this study, we propose that the imaginary part of the electrical susceptibility in the medium is modulated, introduce parameters, and propose optical electromagnetic field analysis by expressing the system in the process as analytic function.
