Magnetic recording medium. |
摘要 |
<p>In the magnetic recording medium according to the present invention comprising a magnetic recording medium layer where a magnetic paint containing Ba ferrite magnetic powder is coated on the substrate, Hc in the oriented direction ranging from 900 to 1500 Oe, the squareness in the oriented direction being 0.80 or more, and the ratio Hr(90 DEG ) / Hr(0 DEG ) of the remanence coercive force Hr(0 DEG ) in the oriented direction (0 DEG ) and the remanence coercive force Hr (90 DEG ) in the direction (90 DEG ) perpendicular to the oriented direction ranging from 1 < Hr(90 DEG ) / Hr(0 DEG ) </= 2.6 - 10<-><3> . Hc are controllable.</p> |
