Adjustable Head Holder

The device as depicted schematically in the figure shows a rotor assembly with means for adjusting penetration, tracking, azimuth and pitch of a rotary head assembly.

Each of the above adjustments is performed separately. The degrees of freedom for the adjustments are possible due to the special design of flexing beam 10. Independent motion is obtained due to the location of adjustment screws relative to the beam 10.

The rotor assembly is comprised of head wheel 12 which is attached to rotor core 14. A motor, not shown, is attached to rotor core 14 for driving the rotor core and its assembly. Cavity 16 is machined on head wheel 12 for seating head support assembly 18. Head support assembly 18 includes head mount 20, plate 22, and head locator bracket 26. Back holder support 28 has beam support slots 30 for receiving one end of flexing beam 10. The other end of flexing beam 10 fits into a support hole, not shown, which is machined into front holder support plate 24. Front holder plate 24 and back holder plate 28 attach to rotor core 14.

In operation, a transducer head, not shown, is seated on surface 32. In order to effectuate the penetration adjustment, screw 34, which has a conical shape and positioned on the back side of head wheel 12, is torqued. The conical surface of the screw 34 abuts the upper end of penetrating pin 36, which results in a camming action between the two surfaces in the direction of arrow 38. Penetrating pin 36 bottoms...
