OTHER BLOCK
Tracking Error Amplifier
The side spot photo diode current input to terminals E and F passes through the E Loop I-V and F Loop I-V
Amps. It is then converted into voltage, in order to gain the difference signal in the Tracking Error Amp. This
portion can perform 0.5X 16 step gain control up to 1X-8X for CD-R and CD-RW. Has the micom programming,
which controls the balance by controlling gain at the E terminal and controls the gain at TEIO.

Focus OK circuit
Focus Ok circuit makes the timing window, which turns on the focus in the focus search state by "output" FOK as
L
→
H if the RF level is above the reference after the difference in DC between and RFO terminals extracted
and compared to the reference DC value.
