In the near-field recording (NFR) system, the gap between the lens and disk will drop down to 100 nm. However, the disk vibration and force disturbance make it difficult to maintain the desired flying height during disk operation, and the lens-disk collision can easily occur. It is proposed in this article to design a hybrid actuator system which combines both advantages of the flying slider used in hard disk drives and the voice coil actuator used in optical disk drives. The dynamic head-disk interface model of the hybrid actuator is first developed, then an adaptive regulation approach is proposed to control the flying height at its desired value despite the unknown disturbances. Simulation and experimental results are presented to illustrate the effectiveness of the proposed flying height control approach.

在近场记录（NFR）系统中，镜头和光盘之间的间隙将降至100 nm。然而，盘振动和力干扰使得难以在盘操作期间维持期望的飞行高度，并且容易发生透镜-盘碰撞。本文提出了一种设计混合驱动器系统的方法，该系统结合了硬盘驱动器中使用的浮动滑块和光盘驱动器中的音圈驱动器的优点。首先建立了混合执行器的动态磁头-磁盘接口模型，然后提出了一种自适应调节方法，以在不受未知干扰的情况下将飞行高度控制在期望值。仿真和实验结果表明了所提出的飞行高度控制方法的有效性。
