A multitrack tape recorder records and replays digital data on a plurality of data tracks (15) by way of record/replay electronics (7), a record head (5) and a replay head (6). Channels (8) corresponding to the tape track (15) are provided for input to and output from the electronics (7). An additional channel (11) carries auxiliary data related to the signals in the channels (8). This data is formatted during recording by the electronics (7) into a block format compatible with the data format on channels (15) and is recorded on a separate dedicated track (16). The auxiliary information may be formatted in labels each of which has an instruction field and a parameter field. The labels can carry a wide variety of information relating to operation of the system. As one example, a label may contain in the instruction field an instruction to increase the playback gain by an amount contained in the parameter field.
Apparatus for recording digital primary data corresponding to signals transmitted through one or more input data channels and recorded on one or more tracks on a recording medium, characterised by means responsive to auxiliary data attached to said primary data, said auxiliary data consisting of control instructions and information related to the said digital primary data, said means carrying out record/reading operations of said auxiliary data on at least one separate track on the recording medium and executing instructions acting upon said digital primary data and said means establishing a formatted structure for the auxiliary data related to the structure of the digital primary data corresponding to the signals.
