Abstract: A non-magnetic layer is interposed between a read head element and an inductive write head element placed on the read head element in a magnetic head. The non-magnetic layer is made of material having a permittivity lower than that of Al2O3. The magnetic head of this type allows interposal of the non-magnetic layer between the read head element and the inductive write head element. Even if a sensing or writing current is supplied to the read head element or inductive write head element, the non-magnetic layer serves to avoid the leakage of the writing current as much as possible. In other words, the crosstalk current flowing to the read head element from the inductive write head element can be reduced. The read head element can be prevented from deterioration.

This can prevent short-circuit from occurring because of thinning the insulating layer.
