A prototype multi-track digital audio recorder is described. Two audio channels are sampled and coded by 14-bit linear quantization. The sampling rate is 44.1kHz, the tape speed is 9.5 cm/sec. and the tape width is 1/4 inch. The channel code (a dc free block code) makes use of the statistics of the audio signal. Precautions are taken to limit the crosstalk in the 16-track ferrite head stack. Error correction and concealment techniques are applied to compensate for random and burst errors.
