Abstract: TRANSDUCER SUPPORT AND STABILIZER 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.

Abstract: Improved magnetic recording apparatus having a rotating flexible registration disc disposed on a flat plate, characterized in that: said flat plate has an elongated throat that opens into said flexible recording disk and has a substantial radial length; a transducer disposed movably to perform radial displacements in said throat; to perform transduction operations with respect to said flexible registration disk; and downward traction means having pneumatic upstream and downstream pneumatic support means, extending from said flat plate towards said flexible recording memory disk and disposed respectively along said throat, opposite sides thereof, for communicating a pulling force downwardly on said flexible recording disk, towards said transducer.

Abstract: FLEXIBLE DISK STORAGE APPARATUS 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.
