报告摘要：

In this presentation, I will talk about some work on optimizing media for 3-dimensional magnetic recording (3DMR). 3DMR is a magnetic recording technology where multiple layers of media are stacked one on top of the other. Each layer in the 3D-stack requires the ability to be written to, and read back from independently from the other layers in the stack. The proposed way of writing to multiple layers, is to use the MAMR (microwave assisted magnetic recording) principle to target different layers in the stack. When the media-stack is hit with one frequency, a particular layer responds to this frequency and becomes "enabled" for writing. The write field then writes only on the layers being targeted by the appropriate microwave frequency. Here we will discuss the optimization process of the media stack and optimization of the spin-torque oscillator that generates the microwave assisting signals for 3D-MAMR.

这次报告将讨论有关优化三维磁记录（3DMR）介质的一些工作。3DMR是一种磁记录技术，其中多层介质的堆叠方式是一层堆叠在另一层之上。3D堆栈中的每个层都需要能够独立于堆栈中的其他层进行写入和回读。提出的多层写入的方法是使用MAMR（微波辅助磁记录）原理来对准堆栈中的不同层。当媒体堆栈被一个频率命中时，一个特定层会响应该频率，并变为“启用”以进行写入。仅在该层被适当的微波频率作为目标时，然后在该区域写入。我们为了使3D-MAMR生成微波辅助信号，而讨论媒介堆栈的优化过程和自旋扭矩振荡器的优化。
