Abstract
A tilted sendust sputtered (TSS) ferrite head has been developed for use with high coercivity metal tape in high recording density VTR systems. 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 application in the field of magnetic recording technology.
