Abstract

PURPOSE:To reduce the copying time of a magnetic tape, by increasing the reproducing speed of a master tape and the revolving speed of a rotary cylinder and also increasing the tape speed and the rotating speed of the rotary cylinder for a slave tape. CONSTITUTION:A master tape 12 drawn out from a cassette 11 is wound on a reproducing cylinder 13 and on a winding reel via a control head 16. The cylinder 13 rotates in a double speed with a cylinder servo system 23 taking a signal from a reference generator 24 and the information of an FG (frequency generator) fitted in the cylinder as an input signal. On the other hand, a capstan 17 controls the tape speed so as to make it 2 times of the recording speed with a capstan servo system 22, and the relation of position between rotary heads 14 and 15 and the magnetic tape 12 of the cylinder 13 can be controlled. Further, an obtained reproducing signal is applied to rotary heads 28 and 29 on a recording cylinder 27 which rotate in double speed of the normal speed and recorded on a slave tape 26.
