| titleOfInvention | Polyester film, polyester film for coating type magnetic recording medium, and magnetic recording medium using them |
| abstract | PROBLEM TO BE SOLVED: To provide a polyester film having excellent running performance and magnetic characteristics, more specifically, excellent suppression of wrinkles, electromagnetic conversion characteristics, suppression of missing bals (MP), and suppression of dropout (DO), and a coating type. To provide a polyester film for a magnetic recording medium and a magnetic recording medium using them. SOLUTION: A film having an outermost layer (A layer) forming a surface (A surface) on which a magnetic layer is provided and an outermost layer (B layer) forming a surface (B surface) on which a backcoat layer is provided on the opposite side of the A surface. A polyester film having a B-side surface roughness SRa of 4 nm or more and 8 nm or less, and a number of protrusions exceeding 0.35 μm of 0.01 / 0.05 mm 2 or more and 0.4 / 0.05 mm 2 or less. To do.
