Abstract

Abstract An arrangement is disclosed for supporting a transducer head on an air bearing. The system includes a planar three point resilient suspension system. The suspension system when acted upon by the air bearing deflects to form a parallelogram support for the transducer which provides desired mobility of the transducer.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 122 words
Apparatus for supporting a transducing head, comprising: a first member to which said transducer may be fixedly mounted, an open frame, first and second generally Z-shaped elongated resilient web members, each having a relatively long central portion and relatively shorter end portions, one end of each of said Z-shaped members, being coupled to a first end of said first member, the other ends of said Z-shaped members being attached to opposite portions of said open frame, and a third elongated resilient web member extending away from said first member in a direction parallel to the central portions of said first and second members, said third member coupling the other end of said first member to a further portion of said open frame.
Claim 2
Dependent Claim 122 words
Apparatus for supporting a transducing head, comprising: a first member to which said transducer may be fixedly mounted, an open frame, first and second generally Z-shaped elongated resilient web members, each having a relatively long central portion and relatively shorter end portions, one end of each of said Z-shaped members, being coupled to a first end of said first member, the other ends of said Z-shaped members being attached to opposite portions of said open frame, and a third elongated resilient web member extending away from said first member in a direction parallel to the central portions of said first and second members, said third member coupling the other end of said first member to a further portion of said open frame.
Claim 3
Dependent Claim 128 words
The invention according to claim 1, wherein said first member, said open frame and said first, second and third elongated resilient members are relatively thin planar members which form with said open frame a suspension system for a transducer, said suspension system in a first condition thereof having said first member and said elongated members disposed substantially in a common plane with said open frame member, said suspension system assuming a further condition in response to a force applied to said first member, in which said first member is disposed in a further plane parallel to said common plane with the central portion of said elongated resilient members being deflected to form substantially parallel arms intercoupling said first member with the open frame member in said common plane.
Claim 4
Dependent Claim 244 words
Apparatus for positioning a transducer with respect to a record medium in response to a fluid bearing formed by the relative movement of the record medium with respect to said transducer in said fluid, comprising: a first support member fixedly mounted in spaced relation with said record medium; a second planar member to which said transducer may be fixedly mounted in a manner to render said second member substantially rigid; a generally rectangular planar open frame member surrounding said second member; means for deflectably mounting said second member to and in the plane of said open frame member, said means including first and second generally Z-shaped resilient planar members, each having a relatively long central portion and relatively shorter end portions, one end of each of said Z-shaped members being coupled to a first end of said second member, the other ends of said Z-shaped members being coupled to opposite portions of said open frame, and a third resilient planar member extending away from said second member in a direction parallel to the central portions of said first and second Z-shaped members, said third member coupling the opposite end of said second member to a further portion of said open frame; and means for mounting said open frame member to said first support member in a manner which allows said second member to be deflected out of the plane of said open frame in response to a force applied thereto by said fluid bearing.
Claim 5
Dependent Claim 244 words
Apparatus for positioning a transducer with respect to a record medium in response to a fluid bearing formed by the relative movement of the record medium with respect to said transducer in said fluid, comprising: a first support member fixedly mounted in spaced relation with said record medium; a second planar member to which said transducer may be fixedly mounted in a manner to render said second member substantially rigid; a generally rectangular planar open frame member surrounding said second member; means for deflectably mounting said second member to and in the plane of said open frame member, said means including first and second generally Z-shaped resilient planar members, each having a relatively long central portion and relatively shorter end portions, one end of each of said Z-shaped members being coupled to a first end of said second member, the other ends of said Z-shaped members being coupled to opposite portions of said open frame, and a third resilient planar member extending away from said second member in a direction parallel to the central portions of said first and second Z-shaped members, said third member coupling the opposite end of said second member to a further portion of said open frame; and means for mounting said open frame member to said first support member in a manner which allows said second member to be deflected out of the plane of said open frame in response to a force applied thereto by said fluid bearing.
Claim 6
Dependent Claim 31 words
The invention according to claim 3, wherein said open frame member, said second member and said means for mounting said second member, form portions of a single piece of resilient material.
Claim 7
Dependent Claim 69 words
The invention according to claim 3, wherein the central portion of said first and second Z-shaped members are disposed parallel to a first axis in the direction of relative motion of said record medium and said transducer, so that said second member and hence said transducer experiences restrained rotatiOnal motion about said first axis but is inhibited from rotational motion about a further axis transverse to said first axis.
