... DVD-RW with CD-RW Capability 1. Description The T0800 is a laser diode driver for the operation of two different, grounded laser diodes for DVD-RAM (650 nm) and CD-RW (780 nm). It includes five channels for five different optical power levels which are controlled by a separate IC. The read channel generates a continuous output level ...
