Magnetic Head Fixture

A magnetic head is precisely positioned during testing and use.

A magnetic head is mounted on an inner ball which rotates about an axis passing through an outer sphere when the lever is turned. The object is to obtain a precise tilt angle phi and skew angle theta for aligning the head gap with reference to a media (not shown). This is particularly useful during manufacturing test of a head, when it is desirable to repeatedly simulate physical media-to-head relationships.

A first guide pin fastened to the outer sphere rides in a control slot in the inner ball to control both angles theta and phi. The extreme limits of the pin in the control slot are held when a second, springloaded, guide pin slides off a raised land in the limit slot. A skew angle theta=+/-25 degrees and tilt angle phi=+/-7 degrees is illustrated.
