Paper Abstract

The design of a digital archival optical mass memory system poses several significant challenges. It must provide high information storage density, allow fast access to the data stored in the memory and provide archival storage of that data. In addition, to be fully responsive to a variety of user needs, the system must be compatible with both the low data rate requirements of computer compatibility and the high data rates of downlink satellite recording. This paper will outline the design approach and detailed subsystem parameters for one such system, the MASTAR archival optical mass memory. The key features of this system include: the use of an acoustic travelling-wave lens system to scan data at rates of up to 50 Mb/s, storage of 109 user bits of information on 148mm X 0.007" fiche, storage of over 1000 fiche in a 17" diameter x 17" high carousel and access to any data block in less than 8 seconds. Experimental results and design considerations for a low cost reader for the system will also be presented.
