 Achieving Double Layer recording meant 
the creation of a new substrate layer that 
sits in between each recording layer that 
was refl ective enough to ‘bounce’ the 
laser beam back when recording to layer 
0, but also transparent enough to let the 
laser beam through to record to layer 1. 
This achievement means 
uninterrupted recording up to 
55 minutes on an 8cm disc.
