MAGNETIC HEAD APPARATUS AND FABRICATION METHOD OF THE SAME

摘要

PURPOSE: A magnetic head apparatus and a fabrication method of the same are provided for preventing heat due to TA(Thermal Asperity) from being transferred to a magnetic resistance sensor. CONSTITUTION: An upper writing pole(11) is provided. A lower writing pole(12) has a writing gap at a certain distance from the upper writing pole(11). A lower shield(14) is distanced from the lower writing pole by a certain distance. A magnetic resistance sensor(13) is installed between the lower writing pole(12) and the lower shield(14). The magnetic resistance sensor(13) may be formed of an AMR sensor(Anisotropic Magneto-resistive Sensor) or a GMR sensor(Giant Magneto-resistive Sensor). A coil(11a) is wound between the upper writing pole(11) and the lower writing pole(12) in multiple times.
