ABSTRACT:
A recording tape cassette which includes two sets of printed material disposed between an outer disk of each tape reel and a wall of the cassette case. The first set of printed material comprises a plurality of lines which cross obliquely with respect to visual fields of the second set of printed material such that in response to the rotation direction of the tape reels, both sets of printed material combine to produce an optical effect of turbulence.
