ABSTRACT:
A transducer head assembly for a video tape machine capable of supporting the magnetic head so that it can be moved transversely to the tape so that the head will be aligned with the magnetic signal track for different speeds and direction of movement of the tape as well as for situations when the tape is stopped. A pair of flexible supporting means are generally triangular shaped and have their rear edges attached to opposite sides of a supporting block and have their free ends connected to a connecting bar upon which the magnetic head is mounted. A coil is attached to the connecting bar and moves between one or more magnets such that when electrical signals are applied to the coil the connecting bar is moved to align the magnetic head. The spacing between the two flexible members is substantial so that a pantograph is formed which assures that the magnetic head moves substantially parallel to the surface of the tape and does not move in an arc.
