Abstract

PURPOSE: To always ensure an accurate reproduction for only the information signal without being affected any of the travelling velocity and the expansion/contraction of the tape, by producing the envelope signal out of the reproduction information and then detecting the frame position on the tape based on the discrete value of the envelope signals.
CONSTITUTION: The video information is recorded by detecting the positions of the blocks 0W255 on the tape 3 and based on the contents of the tape counter. And the video information is reproduced by detecting the frame position on the tape 3 and based on the count contents of the envelope signals after producing the envelope signal of the information signal 82 based on the output of the head 9 and also counting up the envelope counter within the conrol unit 12 and by the envelope signal. Accordingly, only the desired video information can be reproduced at all times out of the designated record position without being affected any of the travelling velocity and the expansion/contraction of the tape 3.
