Abstract
An improved Bernoulli plate for juxtaposition to a rotating flexible magnetic disk so that the disk is rendered substantially rigid by a vacuum formed by the air between the plate and the disk being urged outwardly under the influence of centrifugal force is disclosed. The plate is formed by coining a metal substrate and thereafter electroplating the coined substrate so that any sharp irregularities resulting from the coining operation are smoothed, while the surface is provided with a hard, wear-resistant coating.
