摘要：
An azimuth angle other than zero can occur if magnetic tape vibrates or moves in the tape width direction during recording or playback mode and this can result in azimuth loss which is a function of the track width angle of misalignment and the wave length of the signals. The wider the tape width the greater the azimuth loss and the lower the tape transport speed the greater the azimuth loss. Thus, the present invention varies the track width and speed so as to obtain optimum reproduction fidelity by combining two or more heads to obtain the desired results.
