Polyester film with specified surface roughness, Young's modulus and heat shrinkage for use as substrate for magnetic recording medium |
| abstract |
A biaxially oriented polyester film for magnetic recording media which has (1) a Young's modulus in a machine direction of 5.0 GPa or less and a Young's modulus in a direction perpendicular to the machine direction of 8.0 GPa or more, (2) a surface roughness on one side of 0.3 to 1.5 nm when measured for a measurement area of 246.6x187.5 mum and 0.1 to 3.0 nm when measured for a measurement area of 2.5x1.9 mm and a surface roughness on the other side of 0.6 to 2.5 nm when measured for a measurement area of 246.6x187.5 mum and 0.1 to 5.0 nm when measured for a measurement area of 2.5x1.9 mm, and, (3) controlled heat shrinkage factors in the machine and transverse directions at 105° C. and 150° C. |
