Abstract

Shown is a mount which can position a head in a rotary manner about three axes. This is accomplished by using a mount 10 whose base is a portion of a sphere. A head 12 with its gap 14 is placed at the center of the sphere and the bottom of the spherical mount 10 is placed in spherical saddle 16.

Spherical Mount for Magnetic Head

Shown is a mount which can position a head in a rotary manner about three axes. This is accomplished by using a mount 10 whose base is a portion of a sphere. A head 12 with its gap 14 is placed at the center of the sphere and the bottom of the spherical mount 10 is placed in spherical saddle 16.

Circle 17 (in phantom) represents a plane through the center of spherical mount 10. Gap 14 of head 12 lies in the plane of circle 17. By only using a segment of a sphere, and by mounting the head 12 at the center of the sphere, rotary movement of mount 10 in saddle 16 will position the head in a rotary manner about any of three axes going through the center of the sphere.

Motion of spherical mount 10 in saddle 16 is controlled by arm 18 protruding through slot 20 in saddle 16. Arm 18 is noticeably thinner than slot 20. This difference in thickness permits arm 18 to twist in slot 20 or move laterally in slot 20, to give sufficient rotary adjustment of head 12.

As an alternative, a hole might be positioned in the bottom of saddle 16 and a rod attached to the bottom of the sphere in place of arm 18. Enough play must be allowed between the arm attached to the bottom of mount 10 and the hole in the bottom of the saddle 16, to permit adjustment of gap 14 of head 12 about each of three rotary axes.
