Abstract:
A magnetic recording apparatus for recording a digital signal on a magnetic recording medium by means of a rotary head, comprising:a recording circuit recording said digital signal; and a servo circuit controlling the rotation of said rotary head and the travel of said magnetic recording medium, wherein during N-times long time recording, the travel speed of said magnetic recording medium is set to 1/N of that during normal recording by means of said servo circuit and said recording circuit records one track recording data every N scanning operations of said rotary head, during N-times high rate recording, the travel speed of said magnetic recording medium is set to N of that during normal recording by means of said servo circuit and recording circuit records N tracks recording data every one scanning operation of said rotary head, and in each of the N-times long time recording and the N-times high rate recording, said servo circuit records a tracking signal on said magnetic recording medium at a period corresponding to once per rotation of said rotary head.
