摘要： A non-magnetic substrate, a Cu layer having a film thickness ranging from 0.5 to 10 nm, a Cr layer having a film thickness of 100 nm or less, a magnetic layer made of CoCrPt alloy in which a percentage content of Cr ranges from 12 atoms % to 20 atoms % and a percentage content of Pt ranges from 4 atoms % to 18 atoms %, a protective layer and a lubricating layer are arranged in that order to form a magnetic recording medium. Because the Cu layer is sufficiently thinned, a medium noise is sufficiently reduced, and a medium S/N ratio is sufficiently heightened. Because the film thickness of the Cr layer is 100 nm or less, the medium noise is reduced. Because the composition of CoCrPt alloy is limited in the magnetic layer, the medium S/N ratio is heightened. In addition, it is preferred that another Cu layer having a film thickness ranging from 0.5 to 10 nm be inserted into the magnetic layer to divide the magnetic layer into two layers. In this case, the medium noise is reduced by 20%, and the medium S/N ratio is heightened. Therefore, even though a magnetoresistive effect type magnetic head is used to record or reproduce information in/from the magnetic recording medium, the medium noise is sufficiently reduced, and the medium R/N ratio is sufficiently heightened.
摘要翻译：非磁性基板，膜厚度为0.5〜10nm的Cu层，膜厚度为100nm以下的Cr层，由Cr含量为12的CoCrPt合金制成的磁性层，原子％至20原子％，Pt的百分含量范围为4原子％至18原子％，保护层和润滑层按顺序排列以形成磁记录介质。因为Cu层被充分地变薄，所以中等噪声被充分地减小，并且介质S / N比被充分提高。由于Cr层的膜厚为100nm以下，因此中等噪声降低。由于CoCrPt合金的组成在磁性层中受到限制，所以介质S / N比提高。此外，优选将膜厚度范围为0.5〜10nm的另一Cu层插入到磁性层中，以将磁性层分成两层。在这种情况下，中等噪声降低20％，中等S / N比提高。因此，即使使用磁阻效应型磁头在磁记录介质中记录信息或从磁记录介质再现信息，也能够充分降低介质噪声，提高介质R / N比。

摘要： There is provided a magnetic recording/reproducing apparatus which has an improved reliability for a reproduced signal by eliminating a deformation in a reproduced signal waveform due to a residual magnetization generated in a magnetic head. The magnetic recording/reproducing apparatus has a magnetic recording medium including a magnetic film to which information is magnetically recorded and a thin-film magnetic head including a magnetic pole and a coil provided around the magnetic pole. A current supplying circuit supplies a current to the coil so that a magnetic state of the magnetic pole is stabilized. The current is supplied to the coil after a recording operation has been completed by the thin-film magnetic head. The current may demagnetize the magnetic pole of the magnetic head, or stabilize the magnetic state of the magnetic pole.
