A newly designed two-track magnetic tape head is described, which has high crosstalk rejection between adjoining channels. This permits use of the design in a single head which may be used for full-track, half-track, and two-track stereophonic use. The basic design incorporates crosstalk rejection of 60 db in the mid-audio frequency range. Crosstalk rejection of this order makes-on a practical basis-inter-channel crosstalk as low as or lower than the signal-to-noise ratio in machines of professional quality. Short discussions and explanations are included on the causes of inter-channel crosstalk, including that from transformer action and that from magnetic fields about the tape itself. The head is simple to produce with reproducible characteristics from head to head and channel to channel.
