Self-aligned metal film core multi-channel recording head for tape drives

摘要

A self-aligned multi-channel tape head structure has a non-magnetic ceramic substrate defining an interior longitudinal channel and a plurality of head regions. At least one head leg at each region defines lateral openings to the interior longitudinal channel. Each head region has a thin-film metal magnetic core deposited on an inside wall surface of the ceramic substrate and a magnetic gap in a longitudinal face of the ceramic substrate. A coil of wire is wound around each head leg to provide a magnetic transducer head at each head region.
