DURABIS: Resists Scratches
A primary feature of the hard coating made with DURABIS technology is its superior scratch resistance.
After DVD media was recorded with data, an abrasion test was performed on the recording surface. [Figure 1] shows the resulting error rates.
The DVD featuring DURABIS coating technology demonstrates astonishingly low abrasion. The rise in the PI (Inner-code parity) error rate after multiple runs with an abrasion wheel is extremely low. In comparison to conventional DVD media, discs incorporating DURABIS technology boast approximately 100 times greater scratch resistance.
[Figure 2] shows the results of an abrasion test using a steel wool pad.
Even after 300 passes by a steel wool pad, a Blu-ray Disc (BD-RE135N) with DURABIS hard coating shows virtually no increase in jitter, attesting to its superior ability to resist scratching.
