Abstract
A tape drive control system for a pinch roller-less type tape recorder in which tape drive is implemented by frictional force between the capstan and tape. A mode instruction circuit determines the operational mode of a capstan motor drive circuit which operates a capstan motor which in turn rotates the conveying capstan. Tape run detection means detects the actual tape condition. The mode instruction circuit operates both in response to outputs of the tape run detection means and to switch inputs to control the operational mode of the capstan drive.
