Audiola 8-Track Car Stereo, Car Radio, 1970s
The term Stereo-8 identifies the audio recording process on a magnetic tape. This name is commonly used to indicate the cassettes in which the tape was placed.
This support was used in the 60s and 70s, a period in which the car radio was a popular device. This Audiola has in fact the hole to insert the 8-Track cassettes.
These cassettes were larger than normal tape cassettes and were quite successful in the US until the evolution of technology made them obsolete and started being abandoned in the early ’80s.
