【 摘 要 】

References(6)Cited-By(4)A fundamental study on a digital-data-preservation system featuring a LED-light computer tomography (CT) was successfully performed. With this system, 17 × 17 × 17-bit test data (recorded by femtosecond laser in a 5-mm-thick, flat synthetic fused silica sample) is extracted from 27projections at different angles. The results of annealing tests at 973K (700°C) and 1173K (900°C) imply that the system has the potential for achieving archival lifetime of over one-hundred-thousand years at room temperature. The storage density could be as large as 16.6Mbytes/cm3 if bit pitch is minimized to 10µm.
