摘要 |
<p>A method for forming a magnetic pattern in a magnetic recording medium (101) having a magnetic layer, a protective layer and a lubricant layer formed on a substrate in this order, wherein the method includes a step of heating locally the magnetic layer and a step of applying an external magnetic field (104) to the magnetic layer. The method can form a magnetic pattern of high density in the magnetic recording medium accurately with the simplest way in a short time. Further, magnetic recording medium and a magnetic recording device capable of recording information at a high density can be provided in a short time and in an economical manner. <IMAGE></p> |
