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.

Flexible disk storage apparatus

A toroidal-shaped stabilizer mounts a transducer for controlled penetration into a flexible record media, preferably a record disk. The toroidal-shaped stabilizer has a convex surface facing the flexible disk to be stabilized. The convex surface has an apex in an outer radial portion of the toroidal stabilizer. The toroidal stabilizer can be used in either a multiple disk assembly, with a single disk assembly or any nondisk type flexible magnetic record apparatus.
