AB  - A nearly ideal focused gap field recording technique greatly reduces the problems associated with the lower speeds of the eight-track prerecorded tape cartridges for automotive use. Use of the technique essentially eliminates bias noise, reduces bias erasure or self-demagnetization loss of high frequencies to levels approaching thosse of unbiased recording, and causes only negligible amounts of thickness distortion. The technique is described and its use in ultra-high-speed duplicating equipment is explained.
