Recording and reproducing apparatus having a device for indicating the running time of the remaining length of tape

摘要

In a recording or reproducing apparatus, the indication of the running time of the remaining length of tape of an information carrier (2) in tape form of a tape cassette (1) is made significantly more accurate by relating the length of tape (L2) of the information carrier in tape form in the tape cassette calculated from the supply of tape of the tape rolls (5, 6) in a first arithmetic operation of an arithmetic device (21) to the nominal length of tape (Ln) of the type of cassette of the tape cassette (1) in a second arithmetic operation. The corrected tape thickness (dk) determined therefrom is used instead of the nominal tape thickness in the arithmetic device (23) for determining the remaining length of tape (L2). The accuracy of this time indication then corresponds to the accuracy of the actual length of tape of the information carrier in tape form of the tape cassette (1) with respect to its nominal tape length. <IMAGE>
