JPS54145426A - Magnetic recording reproducer - Google Patents

Abstract

PURPOSE: To expand the range in which a reproducer can be used by enabling a helical-scan type VTR to perform still reproduction or slow reproduction down to a half speed in case of azimuth recording.

CONSTITUTION: Magnetic heads 1A and 1B with operation gaps different in angle are arranged on tape guide drum 11, which is turned at a fixed period, and magnetic tape 4 is caused to run on the rotating circumferences of heads 1A and 1B at a fixed speed slanting at a fixed angle so as to supply video signals to heads 1A and 1B, thereby recording magnetic tracks on tape 4. Further, a couple of magnetic heads 2A and 2B with operation gaps equal in angle to those of heads 1A and 1B and similar magnetic heads 3A and 3B are arranged on the same tape guide drum 14 keeping a difference in level and turned on the same rotation axis, and tape 4 wound aroung the rotating circumferences of heads 2A and 2B, and 3A and 3B slanting at a fixed angle is made to run at a higher speed than recording, so that the regeneration outputs of heads 2A and 2B, and 3A and 3B will be extracted selectively.
