We are developing a holographic memory card drive using thin polymer storage layer on credit card sized plastic carriers. The main features of the card are high storage density, rewritability and resistance to harsh environment (e.g. electromagnetic noise, mechanical intolerance, high temperature and humidity). The optical system of this device uses Fourier holograms to record information. The present communication deals with the optimization of the storage density by computer modeling of the system. The model is based on fast Fourier transformations, taking the parameters of the optical processes into account. The model was used to assess the performance of various parameter sets. The results are tested experimentally. The work suggests that storage density higher than 1 bit/μm2 may be achieved in the thin holograms of this memory card at raw bit error rate values below 10-3.
