ABSTRACT:
Complex magnetic head of the present invention eliminates relative magnetic interference between the magnetic heads and relative gap position drift between magnetic heads. The complex magnetic head has high performance and is compatible with lower rank FDDs. The complex magnetic head comprises R/W core track width regulation grooves (52a, 52b, 53a, 53b) filled with glass, erase core track width regulation grooves (55a, 55b, 56a, 56b) filled with glass, R/W core (18, 22) and erase core (20, 24) between shield members formed by these core track width regulation grooves (52a, 52b, 53a, 53b, 55a, 55b, 56a, 56b).
