ABSTRACT:
A Bernoulli disk storage apparatus includes an elongated slot or groove having a substantial radial elongated portion for movably receiving a transducer. On either side of the groove are air bearing means which induce a pull down force on the record storage disk as it passes over the groove. By varying selected parameters, the medium-to-transducer spacing is held substantially constant throughout the radial extent of a desired recording area. Further, flutter usually associated with a Bernoulli disk at its outer radial portion is eliminated.
