ABSTRACT:
An improved magnetic head enables to reduce a crosstalk values without degrading head wear characteristic of the magnetic head when it is used as a pair of magnetic heads in a magnetic head assembly. The magnetic head has a first and second core sections, each containing at least a magnetic core. The first and second core sections forms a magnetic gap between the respective magnetic cores and a head-tape contact surface by being abutted at distal end surface thereof. The first core section has an approximately L-shaped configuration. The first core section has a head-tape contact core part for forming a part of the head-tape contact surface of the magnetic head and a straight core part extending in an opposite direction of the head-tape contact surface from the head-tape contact surface. The second core section has an approximately C-shape configuration to allow a winding to be provided around the second core section. Length of the head-tape contact core part is made longer than a length of the straight core part in a tape running direction.
