This apparatus is used for automatically bringing a number of magnetic tape cassettes stacked in a loading magazine to a recording and/or playing back station and therefrom to a collecting magazine in such a manner that the lowermost cassette contained in the loading magazine is pushed in a movable container which is between said two magazines and after carried by said container from the plane of the magazines to the recording station. Successively the movable container carries the recorded cassette from the recording station to the plane of the magazines and a transfer mechanism pushes the recorded cassette into the collecting mechanism; simultaneously, the transfer mechanism brings the new lowermost cassette of the loading magazine to the movable container.
