Abstract

Shown is a rotor segmented into permanent section 10 and field replaceable section 12. The field replaceable section carries magnetic heads 14, 16 and 18. Each head is mounted on adjustable mount 20. Adjustable mount 20 for head 16 is shown exploded out of cylinder 22 in which mount 20 rides. Field replaceable segment 12 contains all of the adjustments for proper positioning of magnetic heads 14, 16 and 18. The adjustments to the heads may be made in the factory. The field replaceable segment 12 may then be shipped to the field and installed without further adjustment of the heads.

Field Replaceable Rotating Head Assembly

Shown is a rotor segmented into permanent section 10 and field replaceable section 12. The field replaceable section carries magnetic heads 14, 16 and 18. Each head is mounted on adjustable mount 20. Adjustable mount 20 for head 16 is shown exploded out of cylinder 22 in which mount 20 rides. Field replaceable segment 12 contains all of the adjustments for proper positioning of magnetic heads 14, 16 and 18. The adjustments to the heads may be made in the factory. The field replaceable segment 12 may then be shipped to the field and installed without further adjustment of the heads.

Each head may be adjusted in three dimensions. The adjustments will be described relative to magnetic head 16; heads 14 and 18 can be adjusted in exactly the same manner. First, mount 20 with head 16 slides into cylinder 22. Cylinder 22 has an axis along the radius of the rotor.

To adjust the height that head 16 protrudes above the surface of the rotor, pin 24 inserts into the back of segment 12 to engage slot 26 in mount 20. Pin 24 has a slight cam shape not apparent in the drawing, but sufficient to raise or lower mount 20 when pin 24 is rotated. Effectively, the cam shape of the pin 24 engages the slot 26 and moves mount 20 along the axis of the cylinder 22.

Second, to twist the head 16 in cylinder 22, Allen head screws 28 and 30 are provided. When mount 20 is in position in cylinder 22, screws 28 and 30 will bottom out in the cut 32 in mount 20. By adjusting the penetration of screw 28 relative to screw 30, or vice versa, mount 20 may be rotated in cylinder 22.

The third and last adjustment of the head is accomplished by Allen head screw 34. Allen hea...
