Abstract
A spring retaining clip resiliently urges the back bar core piece of a magnetic head assembly into contact with the back ends of two other core pieces whose front ends define the head gap. Use of the clip permits installation of the head coil on one of the core pieces and installation of the back bar after the core pieces have been secured, ground and lapped in the head housing, thus simplifying the manufacturing process. In a preferred embodiment the retainer clip has a first surface member for engaging or being glued to the side of the back bar, and a pair of resilient tabs for engaging the back ends of the pole pieces when the back bar is installed with the clip holding the back bar and the pole pieces tightly together. A grounding wire for the core can be soldered to the retaining clip.
