M-DISC™ Longevity - US Department of Defense Survey of the DVD+M 4.7GB 1,000 Year Logo Top Surface Disc

The U.S. Department of Defense Naval Air Warfare Weapon’s Division facility at China Lake, California, showed interest in digitizing, permanently storing, and providing access to irreplaceable information so, they looked into M-DISCTM technology. Because the M-DISCTM offers permanent data storage technology with DVD compatibility, researchers liked the idea their permanently archived information could be could be accessed easily without the cost and hassle of environmentally controlled stroage conditions. So, they decided to put it to the test. The reported tests were run to ensure that the media would hold-up under the harshest environments over long periods of time. NAWCWD tested five different brands of archival-quality, gold dye-based recordable DVD discs and the M-DISCTM.

“None of the M-DISC™ media suffered any data degradation at all. Every other brand tested showed large increases in data errors after the stress period. Many of the discs were so damaged that they could not be recognized as DVDs by the disc analyzer” (p.i.)

All optical media was required to meet certain performance criteria before testing (Section 2.2, p.6-8). A total of 25 discs from each of six brands, including M-DISC™, were tested, for a total of 150 test discs. Drive and disc performance was analyzed to determine which drive/disc combination provided the best write quality for each brand of media (Table 2-5, p.7). The M-DISCs™ were burned using the M-DISC READY™ drive. “None of the Millenniata media suffered any data degradation at all.” There was great variation in quality with some brands of dye-based discs, even within the same batch. For two brands in particular, it took more than 50 discs each to get the required 25 for the test (Table 3-2, pg. 27). The discs were stressed in a combined temperature, humidity, and light cycle (Section 1.2.2, p.3). The discs were subject to the following test conditions in the environmental chamber: 85°C, 85% relative humidity (conditions specified in ECMA-379) and full spectrum light (per MIL Std. 810G) (Figure 1-1, p.3). The test was repeated three times with identical results.
