Abstract

This invention describes the construction of the front surface geometry, where the magnetic tape is being supported. First of all, the notch assumes a trapezoidal shape. The tip of the trapezoid is substantially higher than the width of the tape, whereas the bottom of the trapezoid is slightly shorter than the width of the tape in order to have the compliant guides apply a vertical downward force upon the tape so that compliant guiding can be achieved. The notch profile conforms to the profile of the compliant button. This matching or conforming minimizes the unsupported space/region for the tape. In this manner, the tape buckling was entirely eliminated. The profile of the notch can be curvillinear as shown, in order to achieve optimum tape guiding. (Figure ).

Notch Air Bearing Profile

      This invention describes the construction of the front surface
geometry, where the magnetic tape is being supported.  First of all,
the notch assumes a trapezoidal shape.  The tip of the trapezoid is
substantially higher than the width of the tape, whereas the bottom
of the trapezoid is slightly shorter than the width of the tape in
order to have the compliant guides apply a vertical downward force
upon the tape so that compliant guiding can be achieved.  The notch
profile conforms to the profile of the compliant button.  This
matching or conforming minimizes the unsupported space/region for the
tape.  In this manner, the tape buckling was entirely eliminated.
The profile of the notch can be curvillinear as shown, in order to
achieve optimum tape guiding.  (Figure ).
