Abstract
Various embodiments herein include utilities that facilitate the substantially flat and aligned mounting of optical tape segments on testing drums to increase testing accuracy of the tape segments. In this regard, a drum for testing optical tape media is disclosed having a substantially planar portion onto which first and second ends of an optical tape segment may be mounted to thereby secure the entire tape segment around an outer testing surface of the drum. Also disclosed is fixture that may be used to precisely mount and secure the tape segment over the outer mounting surface of a drum in a manner that reduces axial run-out and wrinkling of the optical tape.
