DESCRIPTION
'DX-6830_
Peak setting input of phase correction of focus track-
ing.
This terminal is flowed the current so that the focus
search, tracking jump. and sled kick height is decided.
Inner switch selection input terminal,
This terminal is used when a track jump.
The sled runaway prevention circuit operates at the
low tevel.
Mid-point voltage input terminal.
Serial data transfer clock input from microprocessor.
Latch input from microprocessor.
Connect the capacitor between pin 9 and this pin when
the high frequency gain of focus servo is dropped.
