发明名称 Process and device for recognizing tape cassettes of different playing times
摘要 A method for the determination of the cassette type of a cassette, which contains a recording medium in the form of tape for recording and/or replaying information using an apparatus having a measurement device for measuring the tape thickness and the tape length of the recording medium, and for producing a control variable for indicating the cassette type or for initiating cassette-type-dependent functions of the apparatus. The steps include determining a value for the tape thickness, determining a value for the tape length, and logically linking the value for the tape thickness and the value for the tape length to one another, to ascertain the cassette type.
