WebThe ferrite surfaces of rotating magnetic heads were found to have been work-hardened to different degrees depending upon the abrasiveness of the flexible recording media used. For the more abrasive tape, the work-hardening was less than for the less abrasive tape. Associated with the increase in microhardness was decreased signal read-back and … Webwear. All heads in the SL Series are "high density ferrite" heads for the ultimate in recording and playback efficiency. These heads are fabricated using techniques similar …
