Abstract: For use in obtaining and maintaining evidentiary integrity as admissible evidence of audio and/or video recorded factual events on a recording tape, feed and a take-up reels each has two paired separate female bearing surfaces. For each of the feed reel and the take-up reel when utilized in paired or cassette arrangement, one of the paired two female bearing surfaces is of a differing shape and/or dimension than the remaining one. One of the paired female bearing surfaces is permanently detachably from the other. The other of the paired female bearing surfaces is inaccessible for the spindle-gear driving thereof by a drive spindle prior to removal or detachment of the initially utilizable drive or feed surface(s). The feed reel removable female bearing surface has a different size or shape or inner diameter of the female bearing surface than that of the female bearing surface of the drive reel.
