| titleOfInvention | Magnetic recording medium |
| abstract | (57) [PROBLEMS] To provide a magnetic recording medium having excellent electromagnetic conversion characteristics, particularly improved error rate in a high-density recording region, and excellent in productivity and running durability. To provide a coating type magnetic recording medium with low noise and excellent storability in a recording / reproducing system combined with a head. A magnetic recording medium for reproducing a recording signal by a magnetoresistive magnetic head (MR head), wherein a magnetic layer mainly composed of a ferromagnetic powder and a binder is formed on a support. An atomic force microscope (AF) is formed on the surface of the magnetic layer. 10) protrusions with a height of 30 nm or more measured by M) 0/900 μm 2 or less, the magnetization reversal volume V of the magnetic layer is (0.1-5) × 10 −17 ml, and the magnetic layer has a coercive force of 2000 Oersted (159 kA / m) or more, The support is composed of a polyester resin (A) and a polyetherimide resin (B), the extrapolation glass transition start temperature (Tg-onset) is 90 to 150 ° C., and The central surface average roughness (SRa) on the magnetic layer forming surface side is 0.5. A magnetic recording medium, which is a biaxially oriented polyester film having a thickness of ˜4 nm. |
