A thin film magnetic head having excellent recording characteristics is
provided. In a structure of the thin film magnetic head, a thickness
L.sub.T (.mu.m) of a top pole chip and a distance L.sub.D (.mu.m) between
a position of a front edge surface of a top yoke and a position of an air
bearing surface are adapted to satisfy L.sub.D.gtoreq.L.sub.T -2.0 (.mu.m)
(L.sub.D.gtoreq.0, L.sub.T <0). In the thin film magnetic head having
such structural features, the above-mentioned thickness L.sub.T and
distance L.sub.D having an influence upon recording characteristics are
optimized, and thus the occurrence of side erase during recording can be
prevented.
Una cabeza magnética de la película fina que tiene características excelentes de la grabación se proporciona. En una estructura de la cabeza magnética de la película fina, un grueso L.sub.T (mu.m) de una viruta superior del poste y una distancia L.sub.D (mu.m) entre una posición de una superficie delantera del borde de un yugo superior y una posición de una superficie sustentadora de aire se adaptan para satisfacer L.sub.D.gtoreq.L.sub.T -2.0 (mu.m) (L.sub.D.gtoreq.0, L.sub.T
