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.
Claims7
In a flexible disk recording device wherein a stack of flexible disks are mounted for rotation on a spindle and a splitter means is provided for spreading apart any two directly adjacent disks by deflecting a portion of said stack toward one end of the spindle, the improvement comprising:
- a restraint means for developing a restraining force to counter the forces of deflection, said restraint means situated in juxtaposition to a small arcuate portion of the outer surface of the end disk in said stack at the end toward which said portion is deflected, said restraint means angularly positioned subsequent to said splitter means in the direction of disk rotation.
