Which of the following is the BEST way to handle obsolete magnetic tapes before disposing of them?

A.
Overwriting the tapes

B.
initializing the tape labels

C.
Degaussing the tapes

D.
Erasing the tapes

Explanation:
The best way to handle obsolete magnetic tapes is to degauss them. This action leaves a very low residue of magnetic induction, essentially erasing the data from the tapes. Overwriting or erasing the tapes may cause magnetic errors but would not remove the data completely. Initializing the tape labels would not remove the data that follows the label.
