The NASA Data Systems Technology Program is using the recent advances in optical disk storage technology to develop a prototype centralized archive for data collected by scientific satellites. Currently under development for Marshall Space Flight Center, the NASA Data Base Management System (DBMS) will ultimately demonstrate the feasibility of ingesting and recording data at rates up to 50 megabits per second and of retrieving and transferring the recorded data to a diverse community of users. A major component in the DBMS is an optical disk system which provides on-line storage for 1013 bits of data.
