Flexible optical disks (FODs) can be rotated at 15,000 rpm and have the capability of recording at 250 Mbps, the rate necessary for a high definition video recorder system (HD-D5). FODs rotating at 15,000 rpm must be set close to (within about 100 μm) the stabilizer to suppress the axial run-out. Under this severe condition, FODs risk collision with the stabilizer when the rotation starts or stops. To overcome this problem, we developed a new stabilizing method that can suppress the axial run-out while keeping a sufficiently wide clearance between the disk and stabilizer by restricting airflow to the stabilizer. |
