Abstract
PURPOSE: To obtain a high-quality reproduced picture which does not cause the screen distortion even with the static reproduction and the normal speed reproduction, by securing a long-time recording in which the tape is fed under one- to- αH/0.5m compared with the normal recording time.
CONSTITUTION: Here A has tracing from 1 of (a) of track A obliquely up to B-track 525. When one head reaches obliquely from 1 up to 525, the other head resproduces obliquely the next track from 262.5 of track B. In such way, no fraction is caused to the horizontal synchronous signal to be produced, and accordingly no screen distortion is caused. Therefore, the tape speed at the signal recording time is set substantially to one-to-αH/0.5m of the normal recording time in the long-time mode of under one-to-αH/0.2m of the long-time mode recording time (αH: shift number of the horizontal synchronous signal in the tape pattern; m: integer), so no screen distortion is caused even thoutgh the static reproduction or the normal speed reproduction may be given.
