ABSTRACT:
A flying head slider for supporting a magnetic head operative to transmit information into and out of a recording medium has a slider body having a surface to be disposed in faced relationship to the recording medium. Positive pressure generating portions are formed on the surface of the slider body to generate a positive pressure during rotation of the recording medium relative to the slider body. A bearing is formed in the fluid-inlet end of each positive pressure generating section to enhance a bearing action due to abrupt compression of fluid. A bleed slot is defined between the positive pressure generating sections and has a fluid-inlet end provided with a negative pressure generating means, whereby the slider stably floats a predetermined distance away from the recording medium during rotation thereof to enable the magnetic head to transmit information.
