[sci.electronics] CD audio recording question

I have some idea of how data is retreived from a CD, error corrected,
and converted to analog signal.  However, I have not seen any information
about the recording process.  Obviously, a steep low-pass filter followed
by A/D conversion starts the process.  Does anyone know what kind of
filtration is involved?  Is there a standard specifying how the digitization
process is to be carried out?  Also, is the digitized signal processed
digitally in any way during CD mastering?
