What is a hybrid SACD?


Hi guys, just purchased a Bob Rodriquez Jazz 'Corridor' cd from the local thrift store, and on the back it says 'this hybrid SACD'......., as I have never bought a cd like this before can someone please clarify for me what a hybrid cd is? The sound quality is excellent. Does that also mean a full SACD will sound even better?
Thanking you in advance.

I think we need to say how the lower layer can be "seen" if there is another layer on top of it.

The CD and the SACD playback lasers are different wavelengths (colors). The top layer is transparent at the wavelength used for reading the lower layer.

yes, the SACD layer has high resolution remaster, which will sound better than 16/44,1 version
