Abstract
Abstract An elongated flat strip of insulative material having at one end a central portion, lateral portions disposed on either side of the central portion, and transverse portions joining the lateral portions to the central portion. The central portion protrudes further than the lateral portions. Wire-connecting pads are concentrated in a line across the central portion and the lateral portions. Conductors are arranged along the length of the strip. The ends of the conductors terminate respectively at the different pads. The conductors terminating at the pads on the lateral portions are mounted along the outer edges of the strip and the conductors terminating at the pads on the central portion are arranged along the center of the strip. As a result, the conductors lead to each portion without passing the pads on the other portions. Each transverse portion has a double-reverse bend that places the pads on the lateral portions in a row stepped back from and beside the row of pads on the central portion. The end of the strip lies in a recess in a magnetic head assembly. The head windings are directly connected to the pads.
