Compression zone recording head
First Claim
1. A magnetic head, comprising:
- a first rowbar substrate having a transducing surface and a gap surface;
at least one thin film transducer on the gap surface of the first rowbar substrate, said thin film transducer forming a portion of said transducing surface;
a first closure covering said thin film transducer on a side thereof opposite said gap surface of said first rowbar substrate, said first closure forming a portion of the transducing surface, wherein said first closure is formed of a layer having a thickness in the range of 0.1-200 microns;
a second rowbar substrate having a transducing surface and a gap surface;
at least one thin film transducer on the gap surface of the second rowbar substrate, said thin film transducer forming a portion of said transducing surface; and
a second closure covering said thin film transducer on a side thereof opposite said gap surface of said second rowbar substrate wherein said second closure is opposite to, spaced from, and facing said first closure.

Abstract
A compression zone recording head is provided having the recording tape in contact or near contact with the recording read/write transducer elements in a compression zone of the tape passing over a transducing surface. The compression zone recording head comprises a flat or shallow contour head having a thin, hard, preferably conducting closure to provide wear protection to the transducers. In one embodiment of the invention, the transducers are located in a compression zone region where the recording tape contacts an edge of the transducing surface at a controlled wrap angle. In another embodiment, the transducers are located in a canopy zone region of the transducing surface due to bending of the tape due to the overwrap. The protective closure is preferably made of sputter deposited Al—Fe—Si, or alternatively of a deposited or bonded layer of Al—Fe—Si, Al—O—Ti—C, Zr—O—Ti, Si—N, Si—C or Zr—O.
