... Combo Drives with CD and DVD Writing Capability 1. Description The T0806 is a laser diode driver for the operation of two different grounded laser diodes for DVD-RAM (650 nm) and CD-RW (780 nm) drives. It includes three chan- nels for three different optical power levels which are controlled by a separate IC. The read channel generates a continuous output level whereas channels 2 and 3 are pro- vided as write channels with very fast switching speeds ...
