Abstract

Super-resolution holographic data storage allows us to record and retrieve a data page with a smaller aperture than a Nyquist aperture. This system has a potential to realize a high-density recording compared with a conventional holographic storage system. Recording a phase data page in super-resolution holographic data storage to improve light efficiency is proposed. The phase data page is designed for the super-resolution holographic data storage to suppress the zero-order beam of a signal beam in a Fourier plane. The numerical experiments show the feasibility of the proposed method.
