Abstract:
An improvement in a system for recording and/or reproducing information signals on/from a record carrier, which system comprises an apparatus having a device for recording and/or reproducing information signals on/from said record carrier and a cassette adapted to be inserted into the apparatus, which cassette accommodates said record carrier and comprises at least one indicator; which by means of one of its parameters indicates at least one characteristic value of a fixed element of said record carrier, the apparatus comprising at least one detection device for the detection of the parameter of the indicator, which parameter indicates the at least one characteristic value, wherein the improvement comprises at least one electrical impedance in the cassette as said indicator in said cassette, the impedance value of said impedance defining the parameter for the indication of at least one characteristic value of a fixed element of said record carrier of said cassette, and the at least one detection device of the apparatus is adapted to detect the parameter defined by the impedance value of the at least one impedance.
