摘要： A magnetic recording medium and a method of manufacturing the magnetic recording medium are provided. In order to increase the recording density of the magnetic recording medium, the magnetic recording medium is configured to multiple magnetic layers by consecutively forming a first magnetic layer having a thin film shape and a second magnetic layer comprising patterned magnetic bits. The first magnetic layer has a magnetic anisotropic coefficient greater than that of the second magnetic layer.

摘要： PROBLEM TO BE SOLVED: To provide an improved hall effect element including a ferromagnetic material component capable of being used, for example, as a logic application example executing a digital combination-allowable task and a memory element for a non volatile memory device of digital information in such as a magnetic field sensor. SOLUTION: A hall effect element includes a ferromagnetic material layer 510 which covers a part of a hall plate 520 and being electrically isolated therefrom. The ferromagnetic material layer 510 on the hall plate 520 can be changed by applying an external magnetic field. When the element is used as a memory component, the element is allowed to have two stable magnetization statuses (positive and negative) along an anisotropy axis that can correspond to two different data values (0 or 1).

摘要： Provided are a master recording medium and a method of manufacturing the master recording medium. The master recording medium includes: a plate; and a magnetic layer which is formed on the plate for magnetically transferring of a servo pattern that is to be formed on a magnetic recording medium. The method of manufacturing a master recording medium includes: engraving a polymer layer by nano imprinting to form an engraved pattern corresponding to a servo pattern to be formed on a magnetic recording medium; forming a magnetic layer which fills in the engraved pattern of the polymer layer; forming a back plate layer on the magnetic layer; and performing processing to expose the servo pattern on a surface of the magnetic layer that is opposite a surface of the magnetic layer on which the back plate layer is formed.
