A cassette for tape-shaped record carriers having optically viewable recordings has a housing provided with a pair of opposite but spaced end walls and a pair of opposite but spaced side walls which connect the end walls and one of which is transparent. A pair of tape hubs is rotatably mounted in the housing and a tape is convoluted on and extends between the hubs for travel from one to the other thereof. One of the end walls is provided with an opening through which a recording device has access to the tape so as to provide recordings on the same. A guide arrangement in the interior of the housing guides the tape so that when it travels from one to the other of the hubs it must first pass the opening and thereupon must travel past the transparent side wall so that, when the cassette is inserted into an optical readout device, the recordings on the tape are visible through the side wall.
