<p>PURPOSE:To prevent the change of a magnetic tape speed on a picture head by arraigning a means which presses the magnetic tape when a sound head and the magnetic tape start to come into contact with each other so that the picture head is made to be positioned between the means and the sound head. CONSTITUTION:When the sound head 33a comes into contact with the tape 45 while the picture head 31a is scanning the magnetic tape 45, the picture head 31a is made to be positioned between a special reproducing head 35a and the sound head 33a, and when the sound head 33a starts to come into contact with the tape 15, driving voltage is impressed to a piezoelectric element attached to the special reproducing head 35a, and the tape 45 is pressed by the piezoelectric element. Thus, the tape 15 on the picture head 31a is pulled by the sound head 33a and the special reproducing head 35a, and the tape 45 on the picture head 31a does not generate the change of the speed, and therefore, jitter to be generated when the sound head 33a starts to come into contact with the tape 45 can be prevented.</p> |
