Information signal reproducing apparatus with noise processing

An information signal reproducing apparatus for reproducing an information signal from a recording medium on which an information signal having a predetermined frequency band has been recorded, comprising:

• (A) signal output means for forming and outputting a first signal having a first frequency band and a second signal having a second frequency band higher than said first frequency band, from the signal reproduced from said recording medium;
• (B) first noise removing means for applying a noise component removing processing to the first signal outputted from said signal output means and outputting the processed first signal;
• (C) second noise removing means for applying a noise component removing processing to the second signal outputted from said signal output means and outputting the processed second signal;
• and
• (D) information signal restoring means for restoring the information signal having the predetermined frequency band, by using the first processed signal and the second processed signal.

An information signal reproducing apparatus for reproducing a first information signal having a predetermined frequency band a second information signal having a frequency band higher than the frequency band of said first information signal, from a magnetic recording medium on which said first information signal and said second information signal have been recorded, comprising:

• (A) signal output means for forming and outputting a first signal having a first frequency band which is same as the frequency band of said first information signal and a second signal having a second frequency band which is higher than said first frequency band, from the signal reproduced from said magnetic recording medium;
• (B) first noise removing means for applying a noise component removing processing to the first signal outputted from said signal output means and outputting the processed first signal;
• (C) second noise removing means for applying a noise component removing processing to the second signal outputted from said signal output means and outputting the processed second signal;
• and
• (D) information signal restoring means for restoring the second information signal, by using the processed first signal and the processed second signal.
