(4) MS (internal detection between tracks) adjustment method

Fig. 5

1) MS gain (FF/NOR mode gain) adjustment

→ External resistors R1 and R2

MS gain is expressed by the following equations.

G1 = 10 + 20log

R1 + 100k

[dB]

G2 = 10 + 20log

R2 + 100k

2) MS low-band cut-off frequency adjustment

→ External resistors R1 and R2 and external capacitors C1 and

C2

The external resistors R1 and R2 and external capacitors C1 and C2 should be adjusted to adjust the low-

band cut-off frequency for the MS frequency response.

3) MS high-band cut-off frequency adjustment

→ External capacitor C3

The external capacitor C3 should be adjusted to adjust the high-band cut-off frequency for the MS

frequency response. (In this case, G1 and G2 have the same cut-off frequency.)
