The Digital Memory Unit Writer DMU is a ruggedized optical drive assembly built by Honeywell. The DMU writer is used specifically to write specially formatted map data to militarized Aircraft Optical Disks AOD for use in the ANASQ-l96 Digital Map System consisting of both a Digital Map Computer and a DMU reader of both U.S. and ally AV-8B Harrier and FA-18 Hornet aircraft. The ANASQ-196 and its support equipment including the DMU writers have been in use by the fleet for well over 13 years. Obsolescence problems exist with the ANASQ-l96 and its support equipment. In particular, DMU writers have proven to be much less rugged, reliable, and more sensitive to power fluctuations than DMU readers, particularly in recent years when obsolescence issues have become more prevalent. In addition, only a handful of DMU writers exist less than 15 overall compared to several hundred DMU readers.
