Abstract :
A 0.78 mu m high-power AlGaAs laser diode array has been developed as a light source for a high data transfer rate optical disc memory system. The laser array consists of eight individually addressable channels with both 60 mW CW output power and little thermal crosstalk. 22 Mbit/s parallel read/write operation on a magneto-optical disc has also been demonstrated using the array.
