An input signal is recorded in a recording tape by converting the input
signal to a record signal through the modulation performed at the timing corresponding
to the previously-specified number of tracks per division of signal by using input-signal
converting means 1,2, 3, and 10 and then rotating a head cylinder
8 at a revolving speed lower than the revolving speed of the head cylinder
8 corresponding to the timing for modulation and corresponding to a recording
rate adjusted by the recording-rate adjusting means 12 by using recording
means 7, 8, 9, 10, and 11. Thereby, it is possible to make the configuration
of a head cylinder same even for a system in which the number of tracks per division
of signal differs due to the difference in compressibility.
