... Writable Optical Drives 1. Description The T0820 is a laser diode driver for the operation of a grounded laser diode for writable optical drives. It includes four channels for four different optical power levels which are controlled by a separate IC. The read channel generates a continuous output level whereas channels are provided as write channels with very fast switching speeds. Write current pulses are enabled when a " ...
