<p>PURPOSE:To prevent malfunction at the controlling by recording control signal through an integrator at the time of making a master tape and obtaining the signal having the same information quantity as that of the master from the duplicated tape. CONSTITUTION:The output of a control signal generator 1 is inputted via integrator 2 to a master tape making recorder 3, the signal whereof in recorded by a head 4, whereby a master tape 5 is obtained. This tape 5 is reproduced with the head 7 of a reprducer 6 and the signal thereof is led to a douplicating recorder 8 and is recorded in a duplicating tape 10 by a head 9. Hence, the signal having the same information quantity as that of the master tape may be obtained from the duplicated tape and therefore malfunction may be prevented at the time of performing controlling with the control signal and volume productivity may be enhanced.</p> |
