Abstract
Abstract A solid state data recording system for storing multichannel analog data. is low power system has characteristics similar to a high performance analog tape recorder but has no moving parts and can be easily ruggedized for severe environmental conditions. In the "write" mode analog data are sampled and converted to digital bits of information. These individual bits are stored in a solid state storage medium by coded enabling and address information provided by a controller. The information is played back by reading out these digital bits, converting them to analog form, and then demultiplexing them to their original channels.
