Abstract
Abstract A self-loading air bearing slider for a magnetic transducer head is chamfered across its whole width from its leading edge (12) down to the cross rail (18) to provide a leading tapered section (10). A recessed section (20) trails the cross rail (18) and is defined by that rail (18) and a pair of side rails (14, 16). The lower surfaces of the three rails are co-planar. The side rails are preferably flared (Figures 1b, 1c, 1d) so that they are wider at the trailing edge (26) of the slider to provide an improved pressure profile thereby to allow fast liftoff from a record surface.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
91 words
An air bearing slider for supporting a transducer relative to a moving record medium, the underside of the assembly being formed to provide a pair of spaced apart side rails (14,16;22,24;28,30;40,42) and a cross rail (18) joining the side rails so that there is a recessed section (20) trailing the cross rail and defined on three sides by the three rails, the lower surfaces of the rails being co-planar, characterised in that the slider is chamfered across its whole width from its leading edge (12) down to the cross rail (18).
Claim 2
Dependent Claim
91 words
An air bearing slider for supporting a transducer relative to a moving record medium, the underside of the assembly being formed to provide a pair of spaced apart side rails (14,16;22,24;28,30;40,42) and a cross rail (18) joining the side rails so that there is a recessed section (20) trailing the cross rail and defined on three sides by the three rails, the lower surfaces of the rails being co-planar, characterised in that the slider is chamfered across its whole width from its leading edge (12) down to the cross rail (18).
Claim 3
Dependent Claim
42 words
A slider as claimed in claim 1, in which the side rails flare (22,24) from the cross rail so that each of the side rails is wider at the trailing edge (26) of the slider than where it adjoins the cross rail.
Claim 4
Dependent Claim
47 words
A slider as claimed in claim 1, in which the side rails are formed so that they have corresponding portions (32,34) of constant width adjoining the cross rail and corresponding flared portions (36,38) extending from the constant width portions to the trailing edge (26) of the slider.
Claim 5
Dependent Claim
68 words
A slider as claimed in claim 1, in which the side rails are formed so that they have corresponding portions (Figure Id,32,34) of constant width adjoining the cross rail, intermediate corresponding flared portions (44,46) extending from the trailing ends of the constant width portions and further portions (48,50) of constant width extending from the trailing ends of the flared portions to the trailing edge (26) of the slider.
Claim 6
Dependent Claim
24 words
A slider as claimed in any preceding claim, in which the recessed section and the rails have been formed in a single processing step.
Claim 7
Dependent Claim
17 words
A slider as claimed in any preceding claim, in which the recessed section has a constant depth.
Claim 8
Dependent Claim
32 words
A slider as claimed in any of claims 1 to 5, in which the depth of the recessed section progressively increases from the cross rail to the trailing edge of the slider.
Claim 9
Dependent Claim
28 words
An assembly comprising a slider as claimed in any preceding claim and a magnetic transducer head (52) supported on the trailing edge of one of the side rails.
