A digital data recorder is adapted for receiving a plurality of parallel input data members for defining a single input signal. Any of the input data members may change in identity during the presentation of the single input signal, and the recorder gives priority identity to any input data member which is of the priority identity for any time during the presentation. The recorder produces a serial, digital data output signal comprising a finite sequence of binary data bits in one-to-one correspondence with the parallel input data members, with the binary state of the bit corresponding to the identity of the input member. The serial, digital output signal is suitable for recording on the single channel of a magnetic tape for fully defining the input signal. The recorder is described in detail as adapted for recording the words taken by a shorthand machine.
