Abstract

Abstract 0 In a magnetic information storage device of the type having a slider which moves relative to a magnetic recording medium such as a disk, the slider has a non-rectangularly shaped air bearing surface that provides the slider with a high degree of stability. The non-rectangular shape is preferably either a triangle or a trapezium. The non-rectangularly shaped slider includes a tapered leading edge and a flat vertical surface as its trailing edge. A conventional thin film head element can be deposited on the vertical surface, if the slider is fabricated from ceramic material, or a conventional head element having a wound coil can be disposed on the vertical surface, if the slider is fabricated from ferrite material.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 90 words
A slider (20) for supporting a transducing head - (27) and for use in an information storage device using a rotatable storage medium, said slider having a body on which is formed a tapered air bearing surface (25), characterised in that: the body has two convergent sides (only one shown, 29) such that the body tapers from a wider end (28) towards a narrower end (38); and in that said tapered air bearing surface has a similar taper to that of the body and is substantially coextensive with the body.
Claim 2
Dependent Claim 90 words
A slider (20) for supporting a transducing head - (27) and for use in an information storage device using a rotatable storage medium, said slider having a body on which is formed a tapered air bearing surface (25), characterised in that: the body has two convergent sides (only one shown, 29) such that the body tapers from a wider end (28) towards a narrower end (38); and in that said tapered air bearing surface has a similar taper to that of the body and is substantially coextensive with the body.
Claim 3
Dependent Claim 18 words
A slider as claimed in claim 1, in which the overall shape of the slider is generally triangular.
Claim 4
Dependent Claim 18 words
A slider as claimed in claim 1, in which the overall shape of the slider is generally trapezial.
Claim 5
Dependent Claim 17 words
A slider as claimed in any preceding claim, in which said two convergent sides are bevelled (23,
Claim 6
Dependent Claim 10 words
24) at their junctions with said tapered air bearing surface.
Claim 7
Dependent Claim 10 words
24) at their junctions with said tapered air bearing surface.
Claim 8
Dependent Claim 25 words
A slider as claimed in any preceding claim, in which said narrower end (38) is bevelled at its junction with the tapered air bearing surface.
Claim 9
Dependent Claim 22 words
A slider as claimed in any preceding claim, in which the tapered air bearing surface includes a plurality of surface irregularities (26).
Claim 10
Dependent Claim 19 words
A slider as claimed in claim 6, in which said plurality of surface irregularities includes a plurality of pits.
Claim 11
Dependent Claim 22 words
A slider as claimed in claim 6 or claim 7, in which said plurality of surface irregularities includes a plurality of grooves.
Claim 12
Dependent Claim 48 words
A slider as claimed in any preceding claim in which said wider end (28) is substantially flat and substantially perpendicular to said tapered air bearing surface and carries the transducing head (27). 10. A slider as claimed in any preceding claim, in which said narrower end is rounded.
