| titleOfInvention | Magnetic recording tape |
| abstract | 【Task】 To provide a magnetic recording tape with improved electromagnetic conversion characteristics and practical reliability. [Solution] In a magnetic recording medium having a magnetic layer on one side of a flexible support and a backcoat layer on the opposite side, the support has an intrinsic viscosity of 0.40 dl / g or more and 0.60 dl / g or less, number average It is a polyester film having a molecular weight of 12,000 or more and 24000 or less, and the density of protrusions having a height of 100 nm or more measured by an atomic force microscope (AFM) on the surface of the backcoat layer is 10 to 500 pieces in a 90 μm square, and 50 nm or more. A magnetic recording tape characterized in that the ratio (P50 / P100) of the total number of protrusions (P50) and the total number of protrusions (P100) of 100 nm or more is 10 or more and 100 or less. [Selection figure] None |
