ABSTRACT:
A recording/reproducing apparatus for recording information on and reproducing recorded information from the recording medium of a recording medium cassette comprises a cassette identifying circuit capable of identifying a first recording medium cassette provided with an IC plate provided with an IC chip and a plurality of terminals connected to the IC chip in a specified circuit pattern representing information about the first recording medium cassette and a second recording medium cassette provided with a terminal plate provided with a plurality of terminals connected in a specified circuit pattern representing information about the second recording medium cassette. The cassette identifying circuit identifies the first (second) recording medium cassette automatically on the basis of voltage signals that appear at the plurality of terminals of the first (second) recording medium cassette when the first (second) recording medium cassette is inserted in the recording/reproducing apparatus to enable the user to use the first and second recording medium cassettes indiscriminately.
