Abstract
A carrier plate for use in mounting a pair of magnetic heads at diametrically opposite sides on a rotatable head drum section facilitates positioning adjustments to remove dihedral head positioning error. Independent dihedral position adjustment is made possible by virtue of a specially shaped slot in the carrier plate, which slot is characterized by two guide edges that are perpendicular to the head pair axis and are adapted to closely engage a shaft or other axis-identifying means associated with the drum section. Such guide edges in cooperation with the shaft permit relative movement between the carrier plate and drum section in a direction to correct dihedral error while blocking movement in directions which would disturb other alignment geometries. In a preferred implementation, the carrier plate has a generally disc-like form.
