ABSTRACT:
A combined magnetic tape head having a recording head and a reproducing head disposed in a side by side relationship with a recessed wedge shaped area therebetween. A shielding plate is interposed between the heads to reduce cross feed therebetween. The top portion of the shielding plate is bent into L-shape so that the bent tip confronts the recording head. The remainder of the wedge shaped area is covered with a resin material, or an auxiliary plate can be positioned over the plate extending between the heads. In order to maintain the combined head free from dust accumulation, the top portion of the L-shaped shielding plate or the auxiliary plate is tapered so that it has a substantially trapezoidal cross-section with either straight or curved inclining sides.
