Abstract

Following the development of the optical data storage technology, an important issue of reliability should also be paid attention to. The designing core of the reliability test way is simulating the users’ circumstance and the transporting process. The normal simulating is important but the users’ playing situation is extreme irregular. So the normal simulating is not enough for reflecting the virtual operating status. Few long time playing experiments have been done previously. In fact such kind of long time playing experiment is most similar to the users’ playing situation, and the effect is compositive since such playing is influenced by current surges, electrostatic discharges, even dust. It seems simple but it is important. We use the optical pickup heads to make sets to play DVD disc continuously for long time, and monitor the image and effect regularly. In our experiment, the optical pickup heads have operated continuously for 6000 hours. It suggests that such kind of long time playing as an additional reliability testing means is necessary, especially for the DVD player’s manufacturing company.
