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. It will work well at low, medium or high speeds, but it's main advantage is reliable operation at high speeds (above 3 Meters/Sec or 120 Inches/Second).
