skivorna är ju tvålagrade ett cdlager samt ett lager för sacd
There are three types of Super Audio CD Discs:
Single-layer SACD: Physically, this is a DVD-5 DVD with a 4.7GB high density layer only for stereo and/or multi-channel DSD recording - capable of delivering up to 100 minutes of high resolution stereo or 80 minutes of multi-channel + stereo sound.
Dual-layer SACD: Physically, a DVD-9 DVD with two high-density layers for a total of 8.54GB capacity - thus enabling longer playing times of either 2-channel or multi-channel DSD recording.
Hybrid SACD: This is the most popular of the three. The hybrid disc is somewhat similar to the dual-layer disc in terms of concept, in that it contains a high-density SACD layer and an audio CD layer physically bonded on the same disc. This makes the disc looks like a regular audio CD disc to a CD player or CD-ROM drive.

Interesting to note that whereas most multi-channel audio sources would resort to computerized 'fold-down' of the channels for playback on stereo systems, this is not the case with SACD audio.
Each multi-channel Super Audio CD actually contains both the multi-channel program and a separate two-channel version right from the hands of the producer. In other words, rather than a computerized approximation, you always get exactly what the original artists intended.
D.v.s. om man har enbart tvåkanals stereo så ryms 100 min, om man även har 5.1 så ryms 80 min.
