A dual-stripe element magnetroresistive read head for reading information
from a magnetic tape. The read head includes a first insulating layer, a
first active magnetoresistive layer formed on the first insulating layer,
a second insulating layer formed on the first active magnetoresistive
layer, a second active magnetoresistive layer formed on the second
insulating layer, and a third insulating layer formed on the second
active magnetoresistive layer. The second active magnetoresistive layer
is magnetostatically coupled to the first active magnetoresistive layer.
A periodic structure is formed on a surface of the first insulator layer.
As the remaining layers are formed on the first insulating layer, the
periodic structure is replicated throughout the read head. Thus, the
periodic structure formed on the first insulator layer stabilizes both
the first and second active layers via magnetic domain pinning for both
layers along the edges of the periodic structure.
