Abstract

PURPOSE:To include pieces of information on the running length and time of a tape in a reel-hub diameter designing method, by varying the reel hub diameter. CONSTITUTION:A built-in circuit measures the running time of a tape from hub rotational frequencies of the take-up reel and feed reel of the cassette tape, and the reel hub diameters are made different so that when the ratio of both hub rotational frequencies is 1, a tape take-up diameter is made constant. For example, as for (n) kinds of tapes having a tape thickness S, tape lengths are Ls, and L1-Ln, recording times of the tape Ts, and T1-Tn, and tape-wound reel hub diameters rs, and r1-rn. In this case, tapes with tape lengths L1-Ln are wound in cassettes having new reel hub diameters rq-1-rq-n when tapes q1-qn for reel hub designing obtained by (Ls-L1)/2-(Ls-Ln)/2 are wound around reels with a reel hub diameter rs, obtaining tapes with desired recording times T1-Tn.
