CXA1372BQ/BS
Mirror Circuit
The mirror circuit performs peak and bottom hold after the RFI signal has been amplified.
For the peak hold, a time constant can follow a 30kHz traverse, and, for the bottom hold, one can follow the
rotation cycle envelope fluctuation.
Through differential amplification of the peak and bottom hold signals H and I, mirror output can be obtained by
comparing an envelope signal J (demodulated to DC) to signal K for Which peak holding at a level 2/3 that of
the maximum was performed with a large time constant. In other words, mirror output is low for tracks on the
disc and high for the area between tracks (the MIRR areas). In addition, a high signal is output when a defect
is detected. The mirror hold time constant must be sufficiently large in comparison with the traverse signal.
