Editing Super Audio CD (section)

=== Disc reading ===
[[file:Sacd.svg|thumb|A hybrid Super Audio CD uses two layers and the standardized [[focal length]] of conventional CD players to enable both types of player to read the data]]

Objective lenses in conventional CD players have a longer working distance, or [[focal length]], than lenses designed for SACD players. In SACD-capable DVD, Blu-ray and Ultra HD Blu-ray players, the red DVD laser is used for reading SACDs.{{citation needed|date=March 2022}} This means that when a hybrid SACD is placed into a conventional CD player, the infrared laser beam passes through the SACD layer and is reflected by the CD layer at the standard 1.2&nbsp;mm distance, and the SACD layer is out of focus. When the same disc is placed into an SACD player, the red laser is reflected by the SACD layer (at 0.6&nbsp;mm distance) before it can reach the CD layer. Conversely, if a conventional CD is placed into an SACD player, the laser will read the disc as a CD since there is no SACD layer.<ref name=extremetech2001/><ref name="muszeroldal"/>
