Stiff Stack Head

The magnetic head employs a sandwich structure. In this, read-write and erase core stack assemblies 1 and 2 are bonded between stainless steel stiffener plates 3. These strengthen the assembly and protect the finished pole tips when inserting the assembly in slot 4 of head shoe 5.

The lower edges of the stiffeners are made flush with the pole tips. The assembly can be inserted in the slot of the shoe to an optical flat surface on which the shoe is resting with assurance that the pole tips are located flush with the shoe surface. The thickness of the sandwich is slightly greater than the slot width. This insures that the sandwich remains positioned in the shoe during electron beam welding along the interfaces of joints between the stiffeners and the shoe.

Potting material is added to the shoe. Then the bearing surface of the shoe is flat lapped.
