Embodiments of the present invention help to provide a flying height adjusting type magnetic head slider with reduced influence of a heater coil induction field. According to one embodiment, a magnetic head slider comprises a heater, a read element, and a write element, which are formed on a substrate. The heater is formed between a lower magnetic shield of the read element and the substrate by meandering a heater coil in direction Y going away from ABS. Magnetic fields by generated in direction Y orthogonal to a track width direction X of the lower magnetic field upon energization of the heater coil are offset each other, exerting no influence on the magnetized state in the track width direction X of the lower magnetic shield. A magnetic field hx induced in the track width direction X of the lower magnetic shield is coincident with the magnetizing direction of the lower magnetic shield, acting to maintain the magnetized state of the lower magnetic shield.
