Abstract: A combination flexible web roller guide assembly and an integral centrifugal pump (fan) functional device located inside the roller's outer surface where an air bearing flexible web support Hydrostatic air film is created upon the roller guide's exterior circular surface. The air bearing film is created when a web is mounted onto the roller's exterior surface with web tension applied and the roller's Outer Tube is rotated by some external means. This results in a web support device that possesses the advantages of roller guides AND air bearings, and none of their disadvantages. A highly reliable mechanical device is obtained simply by the incorporation of centrifugal fan-like vanes and an air path from the atmospheric exterior, to inside the outer tube of the roller into spaces between the vanes, and finally through multiple air ports located on the roller's outer tube surface.

Abstract: A golf club head for a golf club is provided. The club can have weights to move the club head center of gravity and club head center of percussion to desired locations to yield desired ball control.

Abstract: A bi-directional magnetic recording/reproduce head surface contour that provides the lowest possible Head-to-Media separation at high media-to-head relative speeds with accompanying best condition head or media wear conditions. The Bernoulli Pockets provide the mechanism that forces the media to fly very close to the recording head gap(s). Depending upon the speed, data rate and capacity goals of the Tape Product the Bernoulli Pocket design can be developed per this invention to provide the required flying conditions. This operating performance is equivalent in both directions selected by a Magnetic Data Recorder. It is intended for use on single, or multiple gap data recorders that record data upon media in a Serpentine manner, in single track or multiple track formats, but may be used in single direction Data Recorders also. The design is not limited to a particular width of tape and can be used on many different data recorders using various width media.
