Shaped rail opposed slider air bearing configuration for increased flying height control of magnetic heads at elevated flexible disk speeds

摘要

The invention provides an exemplary slider arrangement for supporting read and/or write elements in operative relation to a first and a second side of a flexible moving recording medium. The slider arrangement comprises a first slider having leading edge, a trailing edge and a longitudinal axis therebetween. The first slider comprises a first longitudinal rail and a second longitudinal rail. The first and second longitudinal rails each have a face positioned toward the first side of the recording medium. A second slider is provided having an leading edge, a trailing edge and a longitudinal axis therebetween. The second slider comprises a third longitudinal rail and a fourth longitudinal rail which each have a face positioned toward the second side of the recording medium. The first and second sliders are mounted generally opposite each other with the first rail being generally opposite the third rail and the second rail being generally opposite the fourth rail. Further, the first and fourth rails each include at least one longitudinal slot to partition the first and the fourth rails each into at least two sub-rails. At least one of the sub-rails of the first and the fourth rails houses at least one read and/or write element and has at least one portion which varies in width.
