Appeal No. 95-2917
Application 08/082,895
The invention relates to a combined read/write magnetic
head used in a device to read information from and write
information onto a magnetic medium.
The independent claim 1 is reproduced as follows:
1. A read/write magnetic head, comprising:
a substrate of substantially magnetically
impermeable material;
a magnetic read head overlying said substrate,
said magnetic read head including a combination
of a first broken flux guide of magnetically
perme-able material, a second unbroken flux
guide of magnetically permeable material
overlying the first flux guide, and a first
region of substan-tially magnetically
impermeable material posit-ioned between said
first and second flux guides, said first region
of material defining a read gap between said
first and second flux guides at one end of said
read/write magnetic head;
a magnetic write head overlying said magnetic
read head, said magnetic write head including a
combi-nation of a first pole, an overlying
second pole of magnetically permeable material
and a second region of substantially
magnetically impermeable material positioned
between said first and a second poles, said
second region of material defining a write gap
between said first and second poles at said one
end of said read/write magnetic head;
said read/write magnetic head further comprising
a substantially single-domain magnetoresistive
element (MRE) positioned between said first flux
guide and said substrate, said first flux guide
including two flux guide sections, each of which
