16 ABSTRACT OF THE DISCLOSURE A magnetic disk recording system with a combination transducer/slider having reduced effective flying height as measured between the transducer gap and the surface of the recording medium. The slider has a leading end, a trailing end and an air bearing surface extending therebetween. The trailing end is provided with a surface contour which forms a boundary with the air bearing surface near the pole tip region of the transducer. Consequently, the effective flying height of the pole tip region is nearly equal to the flying height of the boundary. The contoured surface can be an angled plane, a transverse notch or a thin overcoat layer with a small angled band. The magnetic transducers may either have flat bottom poles or a bottom pole with a recessed central region.
