Magnetic recording medium, method of manufacturing magnetic recording medium, and magnetic recording/reproducing apparatus |
摘要 |
The present invention provides a magnetic recording medium that has sufficient recording/reproducing characteristics and good write characteristics and can correspond to high recording density, and a method of manufacturing the same. A magnetic recording medium 1 includes a plurality of magnetic recording patterns 2 that is magnetically separated from each other. Each of the magnetic recording patterns 2 includes a low-coercivity region 2a and a high-coercivity region 2b having a coercivity higher than the low-coercivity region, and the high-coercivity region 2b is arranged at the center of the low-coercivity region 2a in a plan view.
