A problem you may encounter trying to use music DAT players for data is
that DAT players designed for sound use error-correction algorithms that
take advantage of the relative linearity (more low frequencies than high)
of most sound sources. If you are missing a few samples, they can be
interpolated without significantly altering the sound. However, if a
few bytes of text, for example, are missing, chances are a waveform
interpolation is not the way to go. Computer data storage devices are
expected to have a far lower toleration for missing data than music
DAT or CD. That's why CD-ROM has a significantly lower capacity than the
number of bytes stored on an audio CD.
