Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
96 words
In a flexure mount for carrying a magnetic recording transducer body adapted to be brought into operative relation with a passing record surface, this mount comprising an elongate flexure strip having a distal tip, a tongue section cantilevered back from this tip, and a pair of like beam-segments flanking the tongue section to join said tip to the proximate end of the mount, the improvement wherein: said beam-segments are each necked-down identically intermediate their length, to exhibit a prescribed minimum width along the roll axis of the mount, whereby to reduce roll bias a prescribed amount.
Claim 2
Dependent Claim
96 words
In a flexure mount for carrying a magnetic recording transducer body adapted to be brought into operative relation with a passing record surface, this mount comprising an elongate flexure strip having a distal tip, a tongue section cantilevered back from this tip, and a pair of like beam-segments flanking the tongue section to join said tip to the proximate end of the mount, the improvement wherein: said beam-segments are each necked-down identically intermediate their length, to exhibit a prescribed minimum width along the roll axis of the mount, whereby to reduce roll bias a prescribed amount.
Claim 3
Dependent Claim
21 words
The combination as recited in claim 1 wherein the segments are each necked-down, and reduced in width, symmetrically along their length.
Claim 4
Dependent Claim
41 words
The combination as recited in claim 1 where the transducer exhibits a number of slider-rails and wherein said "necking-down" is designed and adapted to so reduce "roll bias" as to keep the operative rail-record surface gaps within 5-15% of one another.
Claim 5
Dependent Claim
17 words
The combination as recited in claim 3 where the record surface is that of a disk record.
Claim 6
Dependent Claim
15 words
The combination as recited in claim 4 where the transducer body is a Winchester-type "slider".
Claim 7
Dependent Claim
18 words
The combination as recited in claim 3 where the gap between beam-segments and the tongue section is enlarged.
Claim 8
Independent Claim
99 words
A method of fabricating a flexure mount for carrying a magnetic recording transducer body adapted to be brought into operative relation with a passing record surface, this mount comprising an elongate flexure strip having a distal tip, a tongue section cantilevered back from this tip, and a pair of like beam-segments flanking the tongue section to join said tip to the proximate end of the mount, the improvement wherein: said beam-segments are each necked-down identically intermediate their length, to exhibit a prescribed minimum width along the roll axis of the mount, whereby to reduce roll bias a prescribed amount.
Claim 9
Independent Claim
99 words
A method of fabricating a flexure mount for carrying a magnetic recording transducer body adapted to be brought into operative relation with a passing record surface, this mount comprising an elongate flexure strip having a distal tip, a tongue section cantilevered back from this tip, and a pair of like beam-segments flanking the tongue section to join said tip to the proximate end of the mount, the improvement wherein: said beam-segments are each necked-down identically intermediate their length, to exhibit a prescribed minimum width along the roll axis of the mount, whereby to reduce roll bias a prescribed amount.
Claim 10
Dependent Claim
23 words
The method of claim 7 where the segments are each necked-down, and reduced in width, symmetrically along their length and mount is stamped-out.
Claim 11
Dependent Claim
39 words
The method of claim 8 where the transducer exhibits a number of slider-rails and wherein said "necking-down" is designed and adapted to so reduce "roll bias" as to keep the operative rail-record surface gaps within 5-15% of one another.
Claim 12
Dependent Claim
24 words
The method of claim 9 where the record surface is that of a disk record and where the transducer body is a Winchester-type "slider".
Claim 13
Dependent Claim
16 words
The method of claim 9 where the gap between beam-segments and the tongue section is enlarged.
Claim 14
Dependent Claim
8 words
The product of the method in claim 7.
Claim 15
Dependent Claim
8 words
The product of the method in claim 9.
Claim 16
Dependent Claim
8 words
The product of the method in claim 11.
Claim 17
Dependent Claim
79 words
An "arched" flexure mount adapted for carrying a magnetic recording transducer body adapted to be brought into operative relation with a passing record surface, this mount comprising an elongate flexure strip having a distal tip, a tongue section cantilevered back from this tip, and a pair of like beam-segments flanking the tongue section to join said tip to the proximate end of the mount, the improvement wherein: the beam-segments are reduced in width medially, and symmetrically, in like fashion.
Claim 18
Dependent Claim
79 words
An "arched" flexure mount adapted for carrying a magnetic recording transducer body adapted to be brought into operative relation with a passing record surface, this mount comprising an elongate flexure strip having a distal tip, a tongue section cantilevered back from this tip, and a pair of like beam-segments flanking the tongue section to join said tip to the proximate end of the mount, the improvement wherein: the beam-segments are reduced in width medially, and symmetrically, in like fashion.
Claim 19
Dependent Claim
38 words
The combination as recited in claim 15 wherein said beam-segments are each necked-down identically intermediate their length, to exhibit a prescribed minimum width along the roll axis of the mount, whereby to reduce roll bias a prescribed amount.
Claim 20
Dependent Claim
41 words
The combination as recited in claim 16 wherein the transducer exhibits a number of slider-rails and wherein said "necking-down" is designed and adapted to so reduce "roll bias" as to keep the operative rail-record surface gaps within 5-15% of one another.
Claim 21
Independent Claim
81 words
A method of adapting a flexure mount for carrying a magnetic recording transducer body adapted to be brought into operative relation with a passing record surface, this mount comprising an elongate flexure strip having a distal tip, a tongue section cantilevered back from this tip, and a pair of like beam-segments flanking the tongue section to join said tip to the proximate end of the mount, the improvement wherein: the beam-segments are reduced in width medially, and symmetrically, in like fashion.
Claim 22
Independent Claim
81 words
