Data-Decoding Method Using AT in Multi-level Amplitude Modulation Holographic Memory

摘要

As a next-generation optical archive storage device for 8K video, we have been researching and developing holographic memory. Recent studies have focused on multi-level code instead of binary code to increase the recording capacity and the data-transfer rate. Multi-level amplitude recording requires a novel reproduction method which can demodulate the signal accurately, even when the optical noise is superimposed on the signal. In this report, we introduce our demodulation method using Al (Artificial Intelligence) for realization of a multi-level amplitude recording system.
