SACD - Super Audio CD

Super Audio CD comes in different flavours.  One HD (High Density) layer, Two HD layers, or the hybrid disc which contains a HD layer and a normal Audio CD layer.  The HD layer(s) contain(s) high quality audio, often in more than one channels.  Special SACD equipment is needed to read and play the audio from the HD layer(s).

Normal CD/DVD-ROM drives will not mount SACD discs but in case of the hybrid disc they should see one layer and detect the CD as a 'normal' Audio CD.
That seems to work out great except (in my experience) PIONEER DVD-ROM drives have problems.  They mistakenly mount the CD as DVD and none of the data is accessible.
