Biaxially oriented polyester film for magnetic recording media |
| abstract |
(57) [Summary] [Structure] At least one film has a height of 200 1100 protrusions of ~ 400 nm / 0.1 mm 2 or more, And 600 protrusions with a height of 400 nm to 600 nm / 0.1 mm 2 or less, and three-dimensional average surface roughness (S Ra) is 15 to 55 nm, center line average surface roughness (Ra) Is 10 to 30 nm, and a biaxially oriented polyester film for a magnetic recording medium. [Effect] The biaxially oriented polyester film for magnetic recording media of the present invention has good scratch resistance when used as a magnetic recording medium, and therefore exhibits an effect in repeated use such as household VTR video tapes. It is a thing. |
