1-2. Procedure of focus activation
For description, suppose that the polarity is as described below.
a) The lens is searching the disc from far to near;
b) The output voltage (Pin 5) is changing from negative to positive; and
c) The focus S-curve is varying as shown below.
The focus servo is activated at the operating point indicated by A in Fig. 3. Ordinarily, focus searching and
turning the focus servo switch ON are performed when the focus S-curve transits the point A indicated in Fig. 3.
To prevent misoperation, this signal is ANDed with the focus OK signal.
In this IC, FZC (Focus Zero Cross) signal is output from the SENS pin (Pin 27) as the point A transit signal.
Focus OK is output as a signal indicating that the signal is in focus (can be in focus in this case).
Following the line of the above description, focusing can be well obtained by observing the following timing
chart.
The broken lines in the figure
indicate the voltage assuming
the signal is not in focus.
