| titleOfInvention | Biaxially oriented polyethylene-2,6-naphthalate film for magnetic recording media |
| abstract | [57] [Problem] [PROBLEMS] Despite a thin film and high mechanical strength, dimensional change in the width direction is small and there is little delamination on the film surface, so that adhesion to a magnetic layer is good and output characteristics are high. The present invention provides a biaxially oriented polyester having a low error rate and excellent characteristics when used as a final product of a magnetic recording medium, particularly a digital video tape. SOLUTION: The thickness of the film is less than 7 μm, the Young's modulus in the vertical direction is 850 kg / mm 2 or more, and the Young's modulus in the horizontal direction is 550 kg / mm 2 or more. The heat shrinkage when kept for 0 days is 0. 01% or less, and the refractive index in the thickness direction is 1.48. A biaxially oriented polyethylene-2,6-naphthalate film for a magnetic recording medium, characterized in that the number is 5 or more. |
