Holographic read-only memory

We describe the three-dimensional holographic optical disc system for application as read-only memory. Several systems design issues are discussed including imaging optics, storage density, readout rate, and the alignment servo system. We demonstrate 40 bits/μm2 surface density and pixel-matched holographic data readout from a 12 cm disc spinning at 600 RPM.
