<p>PROBLEM TO BE SOLVED: To prevent the occurrence of cross talk between a recording signal and a reproducing signal even when a head cylinder is reduced by fixing a gap between tracks on a magnetic recording medium with which magnetic heads respectively loaded on first, second head cylinders are in contact simultaneously. SOLUTION: In this magnetic recording/reproducing device, when a digital signal is recorded/reproduced using the first, second head cylinders 1, 2, the rotational speed of the second head cylinder 2 is adjusted by a rotational speed adjustment part 6. Thus, the gap between the tracks is made to be the number of fixed tracks always. Then, the cross talk between the reproducing signal and the recording signal doesn't occur even when respective first, second head cylinders 1, 2 are reduced. Thus, simultaneous reproduction at a recording time and after-recording of a sound signal are performed.</p> |
