Abstract
The front face of a multitrack magnetic head has a stack of track defining pole pairs and spacers between the pole pairs of adjacent tracks. The spacers are slotted, and shields reside in the slots. A chamfer runs longitudinally of the stack. Embracing opposite sides of the stack and parallel to the chamfer, are non-magnetic wing parts, such parts being part of a surround used in the manufacture of the front face. Bonding glass, in the form of a unitary 'lattice' fills the chamfer, and the spacings between the ceramic and shields, and the wing parts and stack. The method for forming the head employs a surround having a depth greater than the depth of the stack, thereby forming a basin for accepting the bonding glass.
