摘要：
In a system (1) for recording and/or reproducing information signals on/from at least one record carrier (13), which system comprises an apparatus (2) and at least one cassette (3) for use in the apparatus (2), each cassette (3) comprises at least one indicator which by means of one of its parameters indicates at least one characteristic value of an element of the cassette (3), and the apparatus (2) comprises a detection device (97, 101, 78) for the detection of this indicator parameter. At least one electrical impedance (R5, R6) is arranged in a cassette (3) as an indicator of a cassette (3), the impedance value of this impedance defining the parameter for the indication of a characteristic value, and the detection device (97, 101, 78) being adapted to directly or indirectly detect the parameter defined by the impedance value of the at least one impedance (R5, R6).
