Abstract
A digital audio signal recorder for obtaining coded signals having a first check code generator for generating the sum of module 2 for each bit of pieces of predetermined sampled data; and further has a circuit operatively coupled to said generator for arranging the sampled data, a first check code and a second check code at positions spaced on a time axis from each other. This invention also provides a method of generating such a digital audio signal. This invention is advantageous because it makes possible a low rate of redundancy and a simple decode circuit.
