A High-Density Digital Recording System for Underwater Sound Studies.

Abstract

A high-density digital recording system is described that allows the conversion from analogue to digital form of up to twenty input analogue channels, their recording on magnetic tape, their readback from tape, and their transfer to a digital computer. The heart of the system is a standard 14-track analogue instrumentation tape-recorder, of the wide-band type, working in direct-recording mode at a speed of 30 in/s and used for digital recording at a density of about 12 kilobits per inch and per track. A total data recording rate of 2880 kilobits per second is achieved with ten magnetic tracks. The system has been successfully tested during various sea trials and is now fully operational.
