Abstract
A method for recording/reproducing digital signals is provided in which each unit of digital data for each channel is constituted by m bit of standard data and n bits of expansion data, the data of each channel are separated into the above standard data and expansion data, the standard data and the expansion data are distributed to different recording tracks and a multiple track recording is performed by stationary heads, so that the data of each channel may be expanded and the m-bit standard data and the n-bit expasion data for each channel may be handled separately from each other.
