Abstract
A recording/playback apparatus accommodates a recording medium in a cassette shell and performs recording and/or playback with respect to the recording medium cassette provided with a cassette-side antenna connected to an in-cassette memory. The playback apparatus includes a recording/playback mechanism, a cassette holding member, a cassette passing member and an apparatus side antenna. The apparatus side antenna effects communication through the in-cassette memory and the cassette-side antenna. An electric wave transmission portion is formed in a portion of the cassette holding member opposed to the cassette-side antenna. The apparatus-side antenna is arranged in correspondence with the electric wave transmission portion.
