Abstract

PURPOSE: To enable to discriminate whether the tape is recorded in PAL system or NTSC system, by reproducing the control signal recorded on the tape and comparing the frequency with the frequency being the reference.
CONSTITUTION: In the PAL system, the frequency of the control signal when the tape recorded in the first tape speed VP is repreduced in the first tape speed Vp, is 25Hz, and it is 35.64Hz when the same tape is reproduced with the second tape speed VN (NTSC system), and the result is listed on the table including the combination of recording and reproduction. Further, the frequency dividing the frequency of the reference oscillator 1 at the reproduction in VP and VN by 81, is also listed on the table. When the tape recorded in VP is reproduced, the frequency of the control signal is greater than the output signal frequency of the frequency division circuit 3 and in case of VN, it is smaller. Thus, the discrimination of PAL and NTSC can be made.
