The first use of a monolithic array of individually addressable diode lasers as the source for high data rate multichannel optical recording is reported. The development of arrays of high-power constricted-double-heterostructure large-optical-cavity (CDH-LOC) diode lasers for this purpose is discussed. The laser outputs from contiguous elements of such an array were used in an optical recording system to simultaneously store three tracks of data on a trilayer optical disk.
