Abstract
A recording and/or reproducing apparatus which accepts two different sizes of magnetic-tape cassettes each having two juxtaposed reels comprises four drive means mounted stationarily in the apparatus and each comprising a reel spindle and a reel disc. Both the reel spindles and the reel discs are axially movable and, when a magnetic-tape cassette is loaded into the apparatus this cassette is detected by means of the reel spindles which are not adapted to enter into driving engagement with this cassette. The reel spindles and the reel discs which are not adapted to enter into driving engagement with this cassette are moved into an area situated outside the area occupied by the inserted magnetic-tape cassette by the cassette housing.
