how are stereo signals recorded on records and CDs


I've been thinking over the past few days primarily about records and how the groove contains a stereo signal. Can someone explain it to me in simple terms?

I'm also not really sure how the stereo signal, or any signal, is recorded on a CD. I know the signal is converted into a series of 1's and 0's, there still much be at least two sets of data for a stereo signal that are either combined or read individually.

Can anyone explain this process in simple terms but with some specifics?

Thanks

Thank you for the explaination of the vinyl groove.

I wasn't really expecting a mechanical analogy for redbook CD, just wondering if someone could explain how the 1's and 0's work in general. I know the electrical signal is converted into a digital code, but what I don't know is how the bit packs fit in or if it's a single string of data or two parallel stings.

I read somewhere about a piece of equipment (maybe the PS Audio DAC?) that seperated the signal into seperate channel at transport and actually had seperate DACs for each channel. It made me wonder at what point, if ever, the two channels were put together or completely seperate.

Make any sense?
