For recorders like, for instance, VHS recorders there are types of cassette which may look the same but may have different playing times. Identifying the type of cassette concerned is time-consuming and may be somewhat uncertain. It is the aim of the invention, therefore, to shorten the time needed for reliable cassette type display, especially for all tape cassettes for use in a VHS video recorder. The type of cassette concerned is identified by linking a measurement characteristic of the tape thickness with one characterising the length or quantity of type in an evaluation circuit (40) which generates an output signal representing the type of cassette which is taken to the instrument indicator (41) to display the type of cassette. Especially for VHS recorders. |
