Sled Control; Spindle Control; Tilt Control; Disc Loading And Chucking - Sony DVP-M35 Operation Manual

3-3-2. CD Sled Control
CD sled control is exactly the same as the DVD.
However settings in IC506 (DSP:CXD8730R) differ.
3-3-3. CD Spindle Control
As the RF signal is processed inside IC806 (CXD1865), the process from the ARP is the
same as the DVD.
3-3-4. Tilt Control
At CD playing, the tilt control is made using the tilt sensor of optical pickup in a period from
the start of play (start of spindle rotation) to the completion of TOC data reading.
The tilt control in this case is same as tilt servo control by tilt sensor during DVD playing.
The tilt servo is turned off after the completion of TOC data reading.
The tilt servo mode ON/OFF control is done with the tilt servo amplifier in the IC006
(SSI33P3720) on the TK-47 board. (Figure. 3-12)
