A disk laminate includes thin disks laminated to each other, which are to be suctioned and conveyed; and spacers provided between the thin disks to prevent the thin disks from directly contacting each other, the spacers having air permeability.

Disk laminate, disk cartridge, disk loading/unloading mechanism, disk conveying device, disk conveying mechanism, and thin disk driving system

A disclosed disk clamping mechanism includes a turntable fixed on a rotational shaft of a spindle motor to rotate a flexible thin optical disk, a stabilizer member configured to suppress a run-out of the flexible thin optical disk by an applying aerodynamic force to the rotating flexible thin optical disk so as to stabilize the run-out of the rotating flexible thin optical disk, and a clamper movably supported in a center of the stabilizer member in a direction perpendicular to a surface of the flexible thin optical disk. In the disclosed disk clamping mechanism, the flexible thin optical disk is sandwiched between the turntable and the clamper such that the turntable and the clamper rotate the flexible thin optical member sandwiched in-between.
