As flying heights are reduced to 10 nm or less, maintaining good flyability becomes critical to ensuring the robustness of the head–disk interface. One way to reduce the head–disk interference during low flying is to minimize the media portion of

We have conducted pulling and bending tests on individual carbon nanotubes in-situ in a transition electron microscope. Based on our observation of the force required to break the tube, a tensile strength of 0.15 TPa was computed. From corresponding
