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