title: Consumer holographic read-only memory reader with mastering and replication technology.
abstract: What is believed to be a novel holographic design for read-only memory systems allows a compact low-cost consumer drive within a 10 mm drive height, using a lensless phase conjugate readout and a combination of polytopic and angle multiplexing. A two-step mastering method enables production of high-efficiency holographic masters, and fast replication is possible by using only a series of plane-wave illuminations. Mastering and replication techniques are verified experimentally with an array of 125 holograms with no measured bit errors.
