Appeal No. 95-4711
Application 08/128,053
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.
