ABSTRACT:
A slider assembly for supporting a recording element in operative relation to a flexible moving recording medium is disclosed. The slider may have a face including air bearing surfaces positioned toward the recording medium. A recording element may be in an air bearing surface near the trailing edge of the face, wherein there is no other slider or other supporting surface on an opposite side of the recording medium. A vacuum cavity may be formed in the face for creation of sub-ambient pressure to attract the slider toward the recording medium. An air bearing surface may be provided with a transverse pressure contour (TPC) along at least one of its edges for providing flying height control, with the TPC having a step geometry. A mounting device may mount the slider in a biased manner toward the recording medium and urge the slider toward the recording medium.
