Abstract
A read/write head is used with high coercivity and low coercivity magnetic stripe in multiple-track applications. The read/write head includes a plurality of inductively wound read/write gapped cores with a recessed core gap structure, and further includes a shield situated between the cores, such that a non-magnetic space is formed between the shield and each adjacent core. The width of the shield is no greater than the width of the non-magnetic spaces.
