Focus Coil
Voltage applied to the focus coil that is connected to the lens opposes a
stationary vertical magnet. The force generated moves the objective lens
up or down to focus the laser spot on the information layer of the disc.
Laser
A ribbon cable connects the laser assembly to its circuit board. A circuit
board connector clamps the assembly’s ribbon cable. Free the cable
from the connector by pulling the connector tabs on both sides 1mm to-
ward the cable. The connector will slide out..
In this picture the left side of the cable is free from the connector.
In a replacement laser assembly, a spot of solder is placed on the foils of
the ribbon cable (see the focus coil picture) to protect the laser diode from
static damage that will shorten its life. Remove the solder spot AFTER
connecting the laser assembly cable to the circuit board.
