Beschreibung
Zusammenfassung:	A magnetic disc recorder includes a removably mounted lightweight disc having a shallow air chamber over which is fastened a flexible membrane of recording media. The disc is removably held on a turntable and aligned air passages lead to the interior of the chamber from an external scoop which forces air into the chamber upon rotation. Such pressurization expands the membrane to contact a transducer.
