Abstract
In a magnetic recording device and method, a magnetic reproduction method and its method and a tape recording medium, the performance can be improved. In the case of successively and obliquely forming tracks along the longitudinal direction of a second magnetic tape having a width wider than a first magnetic tape and continuously recording recording data for at least two tracks in a digital recording format on each track, each track is to be formed at a predetermined track pitch set based on the recording time and the reproduction signal characteristic. Thereby, recording data based on the digital recording format which is applied to the first magnetic tape can keep a practically sufficient C/N ratio and can be recorded on the second magnetic tape for a long time. And thus, a magnetic recording device and method, a magnetic reproduction device and method, and a tape recording medium capable of improving the performance can be realized.
