Abstract

PURPOSE: To prevent the generation of a noise or dropout, deterioration in S/N, variation in level, etc., by nearly eliminating unevenness of a wound tape by providing partially a tape hub with a concave part equal nearly to the thickness of the tape.
CONSTITUTION: Part of the circumference of hub 2 is provided with semicrescent- shaped notch part 10 and the depth of its concavity is nearly equalized to the tape thickness. Further, the notch 10 can be provided with slot 11. Otherwise the semicrescent-shaped notch is further provided with concave part 12, where stopper (9) is fixed. In the structure like this, when a magnetic tape is wound around this, a surface wound with the next-layer tape is nearly flattened, so that unevenness of the tape will never appear. Therefore, none of an error, deformation in screen, noise, dropout, deterioration in S/N, variation in level, etc., is caused.
