Appeal 2007-3202
Application 10/145,987
The above-quoted text is within the portion of Hines cited by the
Examiner for meeting the requirement of the bias element. (Answer 6:21).
10. In column 7, lines 63-65, Hines further states:
It should also be easy to provide the approximately 0.2T self or
external biasing necessary to obtain a linear response and
higher MR close to H=0.
The above-quoted text is also within the portion of Hines cited by the
Examiner for meeting the requirement of the bias element.
11. The Examiner further stated that “providing bias field is very
well known in the art” (Answer 6:22). In response to that statement, the
Applicants provide no reply.
12. Mizoshita is directed to a magnetic head including a magneto-
resistive element for recording and reproducing signals on a magnetic disk
or tape. (Mizoshita col. 1:9-17).
13. It is not in dispute that Mizoshita discloses a first magnetic
shielding layer 23 and a second magnetic shielding layer 28, on opposite
sides of magneto-resistive layer 26. (Mizoshita, Fig. 1b; col. 3:53 to col.
4:23).
14. Citing Mizoshita (col. 2:15-24), the Examiner determined that
Mizoshita discloses including magnetic shields on opposite sides of the
semiconductor mass to reduce magnetic flux leaking from the magneto-
resistive element, which leakage flux causes damage to information
magnetically recorded on the recording medium. (Answer 7:8-13).
15. The Applicants provide no reply to the Examiner’s
determination that the magnetic shielding layers of Mizoshita are for
