磁记录装置以及高频辅助记录方法
摘要：
本发明提供能够进行稳定的高频辅助记录的磁记录装置以及高频辅助记录方法。本实施方式所涉及的磁记录装置包括：磁记录介质；具有记录磁极、配置于记录磁极的附近的旋转扭矩振荡器以及对记录磁极励磁的线圈的头；向线圈供给与记录数据相应的记录电流的记录电流供给部；向旋转扭矩振荡器通电驱动电流的驱动电流供给部；检测记录数据的模式的模式检测部；和在由模式检测部检测到的记录数据的模式与预定的模式一致的情况下使向旋转扭矩振荡器供给的驱动电流变动的电流控制部。
摘要（英）：

According to one embodiment, a magnetic disk device includes a magnetic recording medium, a head including a recording magnetic pole, a spin torque oscillator provided near the recording magnetic pole, and a coil which excites the recording magnetic pole, a first current supply which supplies the coil with a first current corresponding to write data, a detector which detects a first signal corresponding to the write data, and outputs a second signal in accordance with the first signal, and a second power supply which varies, in accordance with the second signal, a second current supplied to the spin torque oscillator.
