CASSETTE TAPE RECORDING AND/OR REPRODUCING APPARATUS AND CASETTES FOR USE THEREIN A large-sized tape cassette has a width, measured in a transverse direction, larger than the similarly measured width of a standard, relatively small-sized tape cassette and, for the purpose of being adapted to be selectively loaded, in place of the standard cassette, into a tape cassette recording and/or reproducing, the largesized tape cassette has a bottom surface with a plurality of grooves therein extending at right angles to the transverse direction and spaced from each other by a distance equal to the width of the standard, relatively small-sized cassette, and the apparatus includes a cassette holder having a pair of parallel guide rails spaced apart for slidable reception in the grooves of the large-sized cassette or for slidable engagement of confronting surfaces of the guide rails with side surfaces of the standard, small-sized cassette. |
