26-2 VTR用マルチトラック磁気ヘッド

概要

論文の詳細を見る
In a helical-scan recording system, multi-channel data transfer requires many heads aligned precisely in a scanner. A single-tip multi-head greatly facilitates this alignment. The new multi-head, combined with an ETF(Embedded Thin Film) head reported previously, has much smaller magnetic cores than a conventional multi-head. This minimizes the crosstalk that is an inherent problem in the multi-head. Head-tape contact for gap-to-gap distance up to 900μm has successfully achieved by adjusting the tip-radius and head protrusion.
