ABSTRACT:
A flexible disk magnetic recording device wherein a large number of disks are separated by mechanical splitting means to form a space between any two selected disks for the insertion of a read/write transducing head. A restraint device is placed in bearing contact with the outer surface of the deflected portion of the disk stack at the periphery to create a bending moment in the deflected disks to buckle the disks. The restraint is placed at approximately 90 degrees subsequent to the splitting means in the direction of disk rotation, subtends an arc at the disk periphery of approximately 10.degree.-40.degree. and extends inwardly from the periphery one-half to two-thirds the radius.
