Abstract
We have developed an optical disk system constructed from a flexible disk and a stabilizer. The key feature of the system is an extremely small axial runout that has been reduced by 5 μm as a result of the aerodynamic effect of the stabilizer. The system can achieve an axial runout of less than 5 μm and enables a recording signal at a density of 0.13 μm/bit. This system is stable in various curvature disks.
