DECISION ON APPEAL
Appeal No. 95-4711
Application 08/128,053
-2-
This is an appeal from the final rejection of claims
1-4, which constitute all the claims remaining in the
application.
Claim 1 reads as follows:

1. A magnetic recording and reproducing apparatus
having a drum around which a magnetic tape is wound,
comprising:
a rotary head mounted on said drum for helically
scanning said magnetic tape so as to reproduce an information
signal recorded on said magnetic tape;
current amplification means disposed inside said
drum near said rotary head for amplifying a current
representing the reproduced information signal to produce a
first reproducing signal;
lower band suppression means disposed inside said
drum for suppressing low frequency components of said first
reproducing signal to produce a second reproducing signal;
voltage amplification means disposed inside said
drum for amplifying a voltage representing said second
reproducing signal to produce a third reproducing signal;
a rotary transformer having a primary winding
disposed inside said drum for receiving said third reproducing
signal, and a secondary winding disposed outside said drum for
supplying said third reproducing signal received at said
primary winding; and
lower band emphasis means disposed outside said drum
for emphasizing said low frequency components suppressed by
said lower band suppression means in said third reproducing
signal supplied from said secondary winding of said rotary
transformer to produce a fourth reproducing signal.
Appeal No. 95-4711

The Examiner’s Answer cites the following prior art:

Sato et al. (Sato) 4,500,932 Feb. 19, 1985
Higurashi 4,562,492 Dec. 31,
1985
Philipps 5,051,847 Sep. 24, 1991
OPINION
Claims 1, 2, and 4 stand rejected under 35 U.S.C. §
103 as unpatentable over Philipps in view of Higurashi. Claim
3 depends from claim 1 and stands rejected under 35 U.S.C. §
103 as unpatentable over Philipps in view of Higurashi as
applied to claim 1, further in view of Sato.
The examiner proposes to add Higurashi’s lower band
suppression and emphasis means to the inside of Philipps’
drum. However, the proposed combination does not produce the
claimed invention. The claims recite a magnetic recording and
reproducing apparatus having lower band suppression means
inside a drum and a complementary lower band emphasis means
outside the drum. The examiner’s combination would place the
suppression means and the emphasis means both inside the drum.
Appeal No. 95-4711
Application 08/128,053
-4-
We are unable to identify any suggestion for placing
the suppression means inside the drum while placing the
emphasis means outside the drum as recited.
Thus, the rejections will not be sustained.
CONCLUSION
The rejections of claims 1-4 are not sustained.
