Abstract
Abstract The present invention relates to a tape recorder system with a tape recording device and a playback device independently operable in time. The tape recorder system includes a recording sub-assembly provided with a feeding reel and a recording device, and a playback sub-assembly provided with a playback device and a receiving reel. The system according to the present invention also includes a circular intermediate reel between the recording subassembly and the playback sub-assembly, the intermediate reel comprising at its periphery a retractable bearing surface and a drive roller from which the tape is directed towards the playback sub-assembly. The playback subassembly is fastened to the intermediate reel and driven in rotation therewith.
