FUTURE OPTICAL COMPUTER STORAGE-Holographic Memory Section 1– Introduction Every year, we cannot fail to notice how computer systems increase greatly in speed, memory capacity and performance. A computer system bought today is, quite literally, out of date by tomorrow. As computers have become more advanced, the applications that they are used for have increased. Today, large files of sound and image data are frequently being stored. The need for greater data storage and faster data access is always increasing. Although conventional magnetic data storage is adapting well to these growing needs, it is reaching its fundamental limit. Improvements made to these conventional storage methods usually decreases access time. This is one of the reasons why a new technology using optical data storage is being developed. This new technology is called Holographic Memory. Section 2 – What is Holographic Memory? Holographic memory is a promising new storage technology, which offers massive increases in speed and capacity. It also offers extremely fast parallel data transfer. Another promising feature of holographic memory is that there are no moving parts, i.e. no magnetic platters, as used in conventional hard drives. This
