摘要： Embodiments of the present invention help to suppress the effects of thermal fluctuation in a thermally assisted magnetic field recording, and improve recording density. According to one embodiment, a recording area of a magnetic disk is heated and the full width at half maximum of an optical power distribution of a near field light generator is controlled to be 100 nm or less. Thereby, the cooling time of the magnetic disk is made 2 nm or less and the effects of thermal fluctuation are suppressed. Moreover, although an incomplete area of the magnetization reversal at the rear end of the magnetic domain is created with rapid cooling, by creating an overshoot at the rising end of the magnetic field waveform of the magnetic recording head, the incomplete area of the magnetization reversal can be overwritten, which is created at the rear end of the magnetic domain previously recorded by the overshoot magnetic field. Therefore, the expansion of the magnetic transition width can be suppressed, resulting in the recording density being improved.
摘要翻译：本发明的实施例有助于抑制热辅助磁场记录中的热波动的影响，并提高记录密度。根据一个实施例，加热磁盘的记录区域，并将近场光发生器的光功率分布的最大半值宽度控制在100nm以下。由此，将磁盘的冷却时间设定为2nm以下，抑制热波动的影响。此外，尽管通过快速冷却产生磁畴后端的磁化反转的不完整区域，但是通过在磁记录头的磁场波形的上升端产生过冲，磁化反转的不完整区域可以被覆盖，其在由过冲磁场预先记录的磁畴的后端处产生。因此，可以抑制磁转移宽度的扩大，导致记录密度提高。

摘要： A method and instrument for measuring, with a high spatial resolution, a magnetic or electric field that varies repeatedly at high speed. An electron beam is deflected by passage through a magnetic or electric field to be measured and is allowed to pass through a deflection electrode to thereby be deflected in a direction perpendicular to the magnetic or electric field to be measured. A track of the deflected electron beam is detected by a two-dimensional sensor, and a waveform or pattern is displayed wherein a time base and an axis of the magnetic field to be measured are orthogonal to each other.
