Abstract
PURPOSE: To enable the recording and reproducing of a signal corresponding to a drum diameter by performing a timing control by a coincidence detecting circuit for detecting a coincidence between a ROM output and a counter.
CONSTITUTION: An AND-gate 710 is connected on its one input side to an input terminal 707 of a reference signal and on its other input side to a reset signal generating circuit 711 on its output side respectively, while its output side is connected to a 10-dividing counter 702, 36-dividing counter 703, 196 dividing counter 704 and 2-dividing counter 705 respectively on their input sides. The reset signal generating circuit 711 decides whether or not the value of the ROM 712 stored with a value of the number of blocks during an interval of silence corresponding to the drum in its various diameters is coincides with the value of the 36-dividing counter 703 and 196-dividing counter 704, and outputs '1' in case of coincidence. By this method, the recording and reproducing corresponding to the drum with an optional diameter can thus be carried out.
