Abstract: A magnetic recording apparatus comprises a movable magnetisable recording medium (21) having a recording surface, a magnetic transducer (24) and an air bearing slider (10) supporting the transducer, head arm means (17) for supporting the air bearing slider with the magnetic transducer closely adjacent to the recording surface of the magnetisable recording medium, accessing means (19) for moving the head arm means relative to the recording surface of the magnetisable recording medium, and leading and trailing ends and an air bearing surface to the air bearing slider. The apparatus is characterised in that the slider comprises side rails (12,14) disposed along the sides of the air bearing surface of the air bearing slider, the side rails being substantially coplanar and extending from the leading end of the slider part way to the trailing end of the slider, and the side rails each having a tapered section (11) formed on the air bearing surface at the leading end, and each having a maximum width measured normal to the leading end to trailing end dimension of the slider which does not substantially exceed the width of the side rails at the leading end of the slider. The slider further comprises a centre rail (16) disposed along the central region of the air bearing surface, the centre rail being spaced from the side rails by recessed sections (18) which extend from the leading end to the trailing end of the slider, the centre rail having a tapered section at the leading end, and a width measured normal to the leading end to trailing end dimension of the slider which is smallest at the leading end and which is greatest at the trailing end of the slider. With this arrangement the rails (12,14,16) and the recessed sections (18) produce a combined pressure profile when the slider (10) is positioned adjacent to the moving magnetisable recording medium (21) so that the slider assumes an orientation having a predetermined pitch angle and a predetermined spacing with respect to the moving magnetisable recording medium in which the minimum spacing between the slider and the magnetisable medium occurs at the trailing end of the slider.

Abstract: An air bearing slider for supporting a magnetic transducer comprising a pair of coplanar side rails on the sides of an air bearing surface of the slider and a center rail along the central region of the air bearing surface to form recessed areas between the rails which extend from the leading to the trailing end of the slider. All the rails have a tapered section at their leading ends. The side rails have a width that does not exceed the width of the side rails at the leading end, and the side rails extend only part way to the trailing end of the slider. The width of the center rail is small at the leading end and greatest at the trailing end of the slider, where the transducer is supported. SA988053
