title: Holographic page synthesis for sequential input of data.
abstract: Holographic digital data storage has been accomplished for over 16,000 bits per page in a page-organized hologram memory, but without a page composer. Instead, data is input sequentially as it arrives at the memory inputs, one bit at a time, and with random access to any bit address within the page. To do this, a new kind of page synthesizer was developed, and excellent results have been obtained using it to record page arrays of data in Fe-doped LiNbO(3). In addition, certain interesting and surprising effects of recording and reading out data in this material by page synthesis will be described, including a discrete, step by step erasure effect unlike the expected gradual erasure of data by successive multiple exposures.
