Abstract
1,232,129. Magnetic tape cassettes. AUDIO MAGNETICS CORP. 10 Nov., 1969 [19 May, 1969], No. 54857/69. Heading G5R. A cassette containing hubs 48, 49 between which magnetic tape is wound is provided with a sheet 36 having low-friction zones 36a, and a transparent zone 36b arranged across a tapeviewing window (not shown) in the cassette wall. Two sheets are located on opposite sides of the hubs and are preferably bowed so as to contact the tape rolls over regions bounded by lines 42, 43, and are located by notches 53, 54 and pins 46, 47. The sheets are of polyester, acetate or P.V.C. film and the low-friction zones are of graphite which also assists in dissipating static charge.
