Abstract
A composite thin film recording/reproducing head comprises, in an integral laminate construction: a magneto-resistance effect thin film reproducing head having a magnetoresistance effect element; and an inductive thin film recording head. The track width of the magnetoresistance effect thin film reproducing head is greater than that of the inductive thin film recording head. The reproducing output of the composite thin film recording/reproducing head can be enhanced without entailing increase in reproducing output noise and the variation of the reproducing output can be suppressed, so that the composite thin film recording/reproducing head has improved reproducing output characteristics.
