cd burner

What does this mean?..... The disc can't be burned, because the device failed to calibrate the laser power level for this media.

It seems that my mac mini combo drive is failing . When i burn a disk all goes well until I eject the same disk and insert it again in my mac mini then it prompts me to eject the disc because it cannot read it. What can be done ? The mini reads disks burned on other computers but it does not...

Someone told me start a new thread on this topic, so here I am. Assuming the fellow who put up the pictures, is still in the neighborhood. This is the dead drive (burner) I have. Please compare.
