Recording medium and reproducing apparatus for quantized data

A recording medium on which processed quantized data obtained by sampling one channel or multi-channel signals in a time sequential manner is recorded and reproduced, wherein:

• said data recorded on said recording medium has a form in which M-bit sample data of each channel signal is separated into 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, a collection of main words of 2n-th sample data of individual channels is arranged as a main sample S2n1 a collection of main words of (2n+1)-th sample data of individual channels is arranged next as a main sample S2n+1, a collection of extra words of 2n-th sample data of individual channels is then arranged as an extra sample e2n, and collection of extra words of (2n+1)-th sample e2n+1 (where n=0,1,2, . . . ),
• said data is a collection of said main samples S2n, S2n+1 and said extra samples e2n, e2n+1 as an unit, a frame is formed by a collection of a predetermined number of samples and is assigned to one or more audio packets which are arranged, mixed with video packets and sub picture packets, between control packets,
• each of said packets has a predetermined byte length,
• when a plurality of main and extra samples are arranged in each of said one or more audio packets, a top of a first main sample is placed at a predetermined position in each of said one or more audio packets and other samples are sequentially arranged after said first main sample,
• a total byte length of said plurality of main and extra samples is equal to or smaller than a maximum byte length of each of said one or more audio packets,
• when said total byte length is less than said maximum byte length, invalid data of a stuffing byte or a padding packet is inserted in a remaining portion, and
• a pack includes a pack header, a packet and, a packet header, said packet header is attached to a data section in which said sample data is stored in each pack, said packet header includes at least a first access unit pointer, quantization bit data, a sampling frequency, and channel information regarding the quantized data, a pack header is attached to said packet header, said pack header includes information representing a stuffing length.
