Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
A vibration damped transducer head assembly comprising: a fixed linear scale, a transducer head spaced from said scale a nominally fixed distance and movable over said scale; a movable carriage having a canti-levered arm extending therefrom for supporting said head at said fixed distance; means for damping vibration of said head due to to and fro movements of said carriage including a mass of relatively dense material the majority of such mass overhanging said head in a direction away from said carriage and in line with said to and fro movements and including a sheet of energy absorbing material for coupling said mass to said head.
Claim 2
Dependent Claim
106 words
A vibration damped transducer head assembly comprising: a fixed linear scale, a transducer head spaced from said scale a nominally fixed distance and movable over said scale; a movable carriage having a canti-levered arm extending therefrom for supporting said head at said fixed distance; means for damping vibration of said head due to to and fro movements of said carriage including a mass of relatively dense material the majority of such mass overhanging said head in a direction away from said carriage and in line with said to and fro movements and including a sheet of energy absorbing material for coupling said mass to said head.
Claim 3
Dependent Claim
18 words
An assembly as in claim 1 where said mass is composed exclusively of metal in an elongated form.
Claim 4
Dependent Claim
34 words
An assembly as in claim 1 where said energy absorbing material is of the type which the more rapid the deforming impulse which may be applied to the material the lossier the material becomes.
Claim 5
Dependent Claim
27 words
An assembly as in claim 1 where said mass has a weight of the same order of magnitude as said cantilevered arm and said transducer head together.
Claim 6
Dependent Claim
24 words
An assembly as in claim 1 where the overhanging portion of said mass is thicker in cross-section relative to the remainder of the mass.
Claim 7
Dependent Claim
44 words
An assembly as in claim 1 where said carriage also includes read/write heads cantilevered therefrom for sensing a magnetic memory disk, said read/write heads being located in the same vertical plane with respect to the horizontal to and fro movements, as said transducer head.
