... Magneto-optical Drives and Others Description ATR0809 is a laser diode driver for the operation of two different grounded laser diodes for DVD-RW/+RW (650 nm) and CD-RW (780 nm). It includes four channels for four different optical power levels. All channels (channel 1 = read channel, channel write channels) can be controlled by fast switches. The current pulses are enabled when a low signal is applied to the NE pins ...
