ABSTRACT:
A magnetic recording and/or reproducing apparatus is capable of recording or reproducing data at variable speeds. The value of the tape tension applied to a magnetic tape is set in accordance with the data rate of an input data signal received through an input data processing circuit and a recording signal processing circuit or the data rate of an output data signal output through a reproduction signal processing circuit. The data rate can be set to any one of 256, 128, 64, 32, 16 and 10 [Mbps]. The use of a tape tension value that is appropriate to the data rate, and to corresponding head drum rotation and tape advancement rates, allows the distance between a recording track TR and the control signal CTL corresponding to the recording track TR is kept substantially uniform, whereby the compatibility among different data rates is improved.
