A review of the desired properties for a professional magnetic tape indicates that increased output at constant distortion, better and more consistent hi response, and a smoother coated surface would be welcomed features. In addition, certain applications present requirements for an alternate base having additional long-term storage facility and greatly improved shrink and swell factors. This paper will present data and describe production methods used in the manufacture of a new professional tape now available on two types of base supports.

At the time this was published, pretty much all of the information in it was known to engineers at tape manufacturers, but this was likely the first time much of this was actually released to the general public. At the time, audio tape coatings were just slurries of gamma ferric oxide in a binder with no other magnetic material added. Engineers were very worried about particle size, shape, and distribution but the actual science behind optimizing these didn't exist. So this was likely the first open publication describing the effects empirically and it set the stage for later research in more systematic modelling. (Respond to this comment)
