摘要：

Laminated Fe-Ta-N film video heads have been developed, using high wear resistance ceramic. The heads achieve a recording capability more than 1.5dB superior to Sendust heads and more than -35dB overwrite values for 1-mu-m wavelength signals over 2-mu-m wavelength signals with high coercive (> 1500 Oe) metal particle tapes. Sufficient wear resistance is also shown with 21.4 m/s tape head relative velocity for HDTV VTRs. It is expected to be possible to improve the read/write characteristics for the Fe-Ta-N head by magnetoelastic energy control to a negative value.
