Flexible optical disks (FODs) can be rotated at 15,000 rpm and used to record at a high data transfer rate for high-definition video recording systems. However, further improvement to the current rate is required to efficiently copy and transfer video content. We studied the stabilizing mechanism of FODs using an aerodynamic stabilization system to increase the transfer rate at a rotational speed of more than 15,000 rpm. Experimental results demonstrate that the axial run-out of FODs has three phases in state. We also found that it is possible to implement a rotational speed of up to 20,000 rpm.
