High Speed Optical Storage Technology

摘要

The objective of the effort was to investigate and demonstrate by means of abreadboard model, a high performance 14-inch digital optical system with the following specifications: (1) 25 Mbps minimum sustained user data rate; (2) 5.0 GB per side minimum user data capacity; (3) Double-sided media capacity of 10.0 GigaBytes; (4) Magneto-Optic media which is erasable and reusable many times with a design goal of 10,000 write/read/erase cycles; and (5) Effective corrected bit error rate of less than 1 bit in 10(exp 12) bits. In order to achieve a low life cycle cost system, off-the-shelf technology and utilization of commercial developments were employed. This approach was realized in the optical head design and the tracking servo system. Successful completion of this effort has laid the foundation for a next-generation optical jukebox system.
