AN IMPROVED MAGNETIC TRANSDUCER STRUCTURE HAVING REDUCED TRACK WIDTH AND A METHOD OF MANUFACTURING THEREOF

摘要

A transducer and method are described where track width reducing notches are filled with a nonmagnetic material which is heated to or slightly over its softening temperature but below its melting temperature. Concentrated high pressure at discrete locations is applied to the softened nonmagnetic material too enhance flow thereof into the notches.
