Abstract

PURPOSE: To prevent jitter, skew, folds, and cutting of tape, by using aromatic polyamide film in which the tensile Young's modulus broadwise (Ew) is greater than that toward lengthwise (El) and El is a given value or more, as the support of magnetic substance layer.
CONSTITUTION: The aromatic polyamide film expressed in equations I and II (where; X is halogen, NO2, and one of R1WR3 or more is NO2, halogen, and m, n are about 100W1,000, and m/n is about 9:1W1:9) is used as the support. This film is obtained by extending the film obtained through flowing polyamide solution transversally, after extending it longitudinally, so that Ew is ≥1.3 times El, El is about ≥850kg/cm2 and the elongation at break lengthwise is about ≥30%. Thus, this film is especially suitable for magnetic tapes for VTR.
