ABSTRACT:
The invention relates to a deck for a magnetic tape cassette apparatus comprising a capstan drive motor and an axially movable servo rod which is driven by a servo motor via a servo drive. The movement of the servo rod controls functional parts of the apparatus such as a head-mounting plate, a loading mechanism, and a switching mechanism, with the aid of a microprocessor which receives switching signals, and a control device for the servo motor. The micrprocessor derives the positions of a servo rod, a mechanical switching member, and an electrical switch and generates control commands for the apparatus based on the position of these elements.
