摘要： An apparatus and a method for measuring the remanence curve of a magnetic material with high accuracy is disclosed. First and second pulse magnetic field coils generate a rapidly-changing pulse magnetic field in the space where a magnetic material is located. First and second air-core coils generate a space of a zero magnetic field as well as a finite magnetic field gradient around the magnetic material after application of a pulse magnetic field. A detector detects the force generated by the cooperation between the magnetic field gradient and the magnetic moment of the magnetic material. An arithmetic unit 33 determines the residual magnetization characteristic of the magnetic material based on the detection result in the detector.

摘要： A magnetic recording medium suppresses effectively side erasure even when recording dot intervals are reduced. Magnetic dots and a soft magnetic layer are provided on a soft magnetic underlayer with a nonmagnetic layer intervening, so that magnetic dots are separated by the soft magnetic layer, and consequently leakage flux during recording to magnetic dots is absorbed by the soft magnetic layer, side erasure can be suppressed, and moreover the soft magnetic underlayer and soft magnetic layer are separated, so that an influence on recording/reproduction characteristics can be prevented.

摘要： A magnetic recording medium having a high magnetic pattern contrast is manufactured. By changing an acceleration voltage that accelerates ions in a process gas, depths (peak depths D0 and D1) from a magnetic layer 44, at which an injection amount of a target element is the maximum, can be made with set depths even if a film thickness of an ion permeation portion 48, which is a thin film portion of a resist 49, decreases. Since the set depths are achieved for the peak depths D0 and D1, a portion to be processed 43 of the magnetic film 44 is made non-magnetized from a top surface to a bottom surface, and a magnetic portion is separated; thus, the magnetic recording medium with a high magnetic pattern contrast can be obtained.
