Do optical drives have hazardous materials in them?

Optical drives are drives such as CD readers and writers. Although the CDs are made using some materials that are hazardous, the finished product is not hazardous. The drives themselves incorporate lasers, which are used to read the CD, or write to it. These are fully enclosed and do not present a hazard to the user. However, if one were to disassemble such a drive and then power the laser it is possible that the laser beam could be hazardous under limited circumstances. But the the drive would not work to read or write CDs, and would effectively have been destroyed.
