The apparatus includes a recording/playback mechanism portion performing recording and/or playback with respect to a recording medium cassette, a cassette holding member which holds the recording medium cassette, which moves between a recording/playback position near the recording/playback apparatus where recording and/or playback is conducted with respect to the recording medium cassette and a cassette passing position spaced apart from the recording/playback mechanism portion where the passing of the recording medium cassette is effected, and at least the portion of which opposed to the cassette-side antenna is formed of a metal, a cassette passing member which moves between a holding position where the recording medium cassette is held by the cassette holding member and an eject position where the recording medium cassette is inserted and detached in a direction crossing the movement path of the cassette holding member, and an apparatus side antenna for effecting communication through the in-cassette memory and the cassette-side antenna, wherein an electric wave transmission portion is formed in the portion of the cassette holding member opposed to the cassette-side antenna, and wherein the apparatus-side antenna is arranged in correspondence with the electric wave transmission portion.
