CD-RW Detect Method
There are four types of source signals in the method used to read the CD-RW DISC.
1. Focus Error Signal 2. Tracking Error Summing Signal (TES) 3. RFO 4. EQI Tracking Gain Window
outputs(TGH,TGL) are sent to ISTAT1 and ISTAT2 during focus search.
1
Focus Error
The monitor output in the table above is set as the focus error output and the focus error output level comparison
$81XX is sent to ISTAT1 and ISTAT2 to allow the micom to monitor the focus error output.
After $81XX is sent, it possible to monitor because the tracking gain window comparator are used commonly.
With search command ($47), if the intensity of radiation set its target, focus search level is 1Vp-p, and peak value is
0.5V. As the table below, windows level transmit $84CX $513X command, ISTAT1 monitored at 500mV.
2
TES
Set the TES in the table above and read the CD-RW disc the same way as focus error detect.
3
RFO
Set the RFO in the table above and read the CD-RW disc the same way as focus error detect.
Set the EQI in the table above and read the CD-RW disc the same way as focus error detect.
