Abstract
A recording/reproducing method for recording/reproducing digital signals on plural slanted tracks of a tape-shaped recording medium, in which, even if some of the slanted tracks are erased due to junction recording or after-recording, the signals can be reproduced satisfactorily. The input digital signals are divided into upper order bits and lower order bits, and the upper order bits are further divided into upper order side bits and lower order side bits. The data corresponding to the upper order bits, the data corresponding to the upper order side bits of the lower order bits and the data corresponding to the lower order side bits of the lower order bits are recorded in respective different slanted tracks.
