datenspeichergeraet with a flexible speicherscheibe

摘要

Flexible disk record storage apparatus has a chordally perturbed backing plate for inducing a dynamic stiffness in a flexible recording disk rotating immediately adjacent the plate. A head radially movably disposed between the chordal perturbations provides reliable recording and playback. A web portion of the backing plate has a predetermined flatness circumscribing a transducing location for enhancing recording and playback quality.
