Abstract:
A digital information recording apparatus having a first recording mode recording a first digital information signal of a first information rate on a magnetic tape to be fed at a first feed speed and a second recording mode recording a second digital information signal of a second information rate of 1/n times said first information rate (where n is a real number of not less than 2) on the magnetic tape to be fed at a second feed speed of 1/N times said first feed speed (where N is an integer of not less than 2), comprising:a circuit which when said second information rate is less than 1/N times said first information rate, adds a dummy signal to said second digital information signal to make the recording rate of said second digital information signal substantially equal to the recording rate of said first digital information signal; and a circuit which multiplexes an identification signal for identifying whether said digital information signal is said first or said second digital information signal or for identifying whether said recording mode is said first or said second recording mode, on said first or said second digital information signal, for recording.
