| Zusammenfassung: | A tester system includes a tester and a radioactive isotope source. The tester includes a spindle assembly, a disk mounted to the spindle assembly, and a head actuatable over the disk. The radioactive isotope source is positioned in an ionizing location proximate the tester, such that a minimum distance between the radioactive isotope source and an axis of rotation of the disk is less than a radius of the disk. |
