Optisches Laufwerk – Wikipedia

Die Bedeutung der optischen Laufwerken nimmt seit 2010 jedoch stetig ab. Das von Apple 2008 vorgestellte MacBook Air ohne optisches Laufwerk löste noch eine Kontroverse aus, bei Minicomputern ist normalerweise aus Platzgründen kein optisches Laufwerk mehr verbaut, in Modellen ab rund 2015 ist zunehmend oft nicht einmal mehr eine Option auf ein internes optisches Laufwerk vorhanden.

What Is the Optical Audio Port, and When Should I Use It?

The port is typically labeled “optical audio”, “TOSLINK”, “Digital Audio Out (Optical)” or something similar, but you certainly don’t need a label to identify it. The TOSLINK port is distinct among all other ports and looks strikingly like a tiny little doggie door into the bowels of your device. Even more distinctive than shape is the fact that when the device is powered on, you ...
