Abstract
Thin‐film magnetic recording head technologies have been investigated by a number of companies since about 1966 and it appears that now they make the first team, because conventional magnetic heads, in spite of recent great advances, just cannot produce satisfactory data recovery at the desired high bit and track densities. In this paper, batch‐fabricated, thin film inductive transducers for magnetic disk recording are the major topic of discussion. The various proposed thin‐film transducer structures are briefly reviewed and recnet developments in the area of thin‐film inductive transducers are discussed. Particular emphasis is placed on head‐per‐track applications and expected development trends are discussed briefly. It is concluded that thin‐film heads in one form or another will become essential components in future magnetic recording systems.
