| titleOfInvention | Biaxially oriented polyester film and magnetic recording medium |
| abstract | A biaxially oriented polyester film for magnetic recording media, which has (1) a dimensional change between before treated and after treated in a width direction of 0.40% or less when the film is treated at 49 DEG C and 90% RH under a load of 170 (g/12.65 mm) in a longitudinal direction for 72 hours, (2) a crystallinity of 27 to 45%, (3) a temperature expansion coefficient alphat (x 10<-6>/DEG C) and a humidity expansion coefficient alphah (x 10<-6>/%RH) in a width direction of the film which satisfy the relationship (alphat + 2alphah) <= 45, (4) a heat shrinkage factor in a width direction of the film of 0 to 0.7%, and (5) a thickness of 3 to 7 mum. This film is useful particularly for digital data storage of a linear track system, is almost free from an error caused by track dislocation due to a dimensional change in the width of a tape and improves output characteristics. |
