Abstract: A speed plate device that is bonded to a Bernoulli plate for juxtaposition to a rotating flexible magnetic disk so that the flexible disk is rendered substantially rigid by a vacuum formed by the air between the speed plate/Bernoulli plate surface and the disk being urged outwardly under the influence of centrifugal force is disclosed. The speed plate device provides a method and means for spinning flexible magnetic media at high spins without any associated signal loss or modulation normally experienced at these elevated speeds. The speed plate is bonded to a Bernoulli plate and has the advantage of changing the Bernoulli surface, thereby preventing the media from sucking down to the Bernoulli plate at higher speeds. This improvement allows the floppy media to be spun at higher speeds. The speed plate also has a narrow slot that runs radially across the speed plate so that heads can access the flexible magnetic media.
