Recording medium and reproducing apparatus for quantized data

A data arranging method for recording or transferring data, for use in a system for recording or transferring quantized data obtained by sampling one channel or multichannel signals in a time sequential manner and reproducing said quantized data, said method comprising the steps of:

• separating M-bit sample data of each channel signal to a main word consisting of m1 bits on an MSB (Most Significant Bit) side and an extra word consisting of m2 bits on an LSB (Least Significant Bit) side;
• arranging a collection of main words of 2n-th sample data of individual channels as a main sample S2n;
• then arranging a collection of main words of (2n+1)-th sample data of individual channels as a main sample S2n+1;
• then arranging a collection of extra words of 2n-th sample data of individual channels as an extra sample e2n;
• and
• then arranging a collection of extra words of (2n+1)-th sample data of individual channels as an extra sample e2n+1 (where n=0, 1, 2, . . . ), whereby resultant data is recorded on a recording medium or transferred.
