| Tilted Sendust Sputtered (TSS) ferrite heads were developed for the deep density metal formula tape used in high frequency recording VTRs. Because the sendust-ferrite boundary plane is at an angle to the gap plane in the TSS head, the interference peaks in the playback output spectrum caused by the pseudo gap between the sendust and ferrite core are significantly reduced. The improved electro-magnetic characteristics of the head produced from sendust-ferrite composite materials have practical applications in the field of video magnetic recording technology.
