Actually analog recordings genrally contain more information than digital ones. The reason digital recordings are generally held to sound better is that digital playback isn't hampered by tape hiss or lp pops and scratches.

Also the basis of MPEG recording and playback (DVD's, MP3's, etc) is a data compression/decompression program (a codec)which largely depends on "getting something out of nothing". Rather than recording each bit of a sound and/or visual source - only select frames are recorded. The job of the codec is to fill in between these frames, inventing them on the fly based on what precedes and follows each. Because of this process, file sizes are relatively small while the quality of the recording can be quite good.
