ABSTRACT:
A data recording apparatus for recording a digital signal onto a magnetic recording medium at one of a plurality of data recording rates. The apparatus comprises a detection device for detecting a change in value of the digital signal, a first variable current source for generating a first current having a value which is varied in response to a data rate of the digital signal, a second variable current source for generating a second current, a recording head for recording the signal into the magnetic recording medium, a current output device for outputting the second current or an added value of the first current and the second current in response to detection results of the detection device, and a recording head driving device for driving the recording head in response to an output of the current output device and the digital signal so as to enable recording at a desired data rate.
