Abstract

A simple arrangement for mounting closure blocks on a center section replaces the usual high-precision sandwich of materials with a single layer of brazing compound. Thin film transducer elements are mounted between the center section and end sections. Each closure block, usually ferrite, should be magnetically isolated from the main body of the center section. This is usually achieved by placing glass into slots cut around the blocks, a precision operation. Several layers of material are also usually provided to give the desired performance.

Magnetic Head Center Section

A simple arrangement for mounting closure blocks on a center section replaces the usual high-precision sandwich of materials with a single layer of brazing compound. Thin film transducer elements are mounted between the center section and end sections. Each closure block, usually ferrite, should be magnetically isolated from the main body of the center section. This is usually achieved by placing glass into slots cut around the blocks, a precision operation. Several layers of material are also usually provided to give the desired performance.

Here, a gold-copper brazing compound secures the closures to the main body of the center section, while simultaneously providing both the desired magnetic isolation and performance.
