ABSTRACT:
In an information signal recording method for recording one information signal on slant tracks formed on a magnetic tape housed in tape cassette usable in a conventional magnetic recording and reproducing apparatus capable of reproducing another information signal by using a plurality of rotary heads and recording a control signal used as a reference in a tracking control during reproducing operation on the magnetic tape, a digital information signal is recorded by shifting rotation phase of the rotary head which is determined on the basis of a control signal 21a by about 180 degrees with respect to rotation phase of the rotary head during the recording of an analog information signal.
