ABSTRACT:
In a method for recording and/or reproducing digital data, such as digital audio signals recorded simultaneously with video signals, dividing sampling data composed of a plurality of bits into higher order bits and lower order bits, constituting error correction coding blocks by only the higher and lower order bits of the sampling data of a plurality of samples respectively, thereby making it possible to easily realize adaptive error checking in the course of the block-by-block error checking in association with, for example, data criticality.
A sync word and a block address are affixed to the error correction coding block constituted in that manner. Since one block address is formed using the address data of two or more blocks, a broader address space can be obtained even when the bit number of the address area of each block is few. At least one flag bit(s) are provided in each sync word to use said flag bits in the blocks bearing specified block addresses as edit flags to set the edit flags in association with each edit point of digital signals, thereby facilitating discrimination of the editing points to reduce the rate of data discarding.
