Abstract: The changing mechanism is used for flexible recording discs each contained ina rectangular sleeve, the play-back unit for the discs having means for lowering the disc onto a rotatable turntable. The recording disc can be moved almost orthogonal to the plane of movement of the disc lowering device by a transport mechanism moving forwards and backwards. An operating mechanism is positioned between the lowering device and the transport mechanism, such that the drive means for rotating the turntable is operated in dependence on the position of the disc lowering device and the position of the transport mechanism. A separate motor may be provided for the disc lowering device and be controlled in conjunction with the drive motor for the turntable.

Abstract: Positioner for the scanning head, mounted on a carriage, in a recording and/or playback apparatus for disk records, with a cable extending between the carriage and the drive motor, and a spring as counterforce, which positioner comprises a pulley, mounted on the carriage, and two pulleys of different diameter which are mounted on the shaft of the drive motor and to which the beginning and end of the cable are fixed, the pulley system operating on the differential pulley principle, so that greater accuracy of positioning is achieved and less torque has to be produced by the motor.
