  • Adjustment Of The Magnetic Head Position Track Following On Tapes (AREA)

Abstract

PURPOSE: To make it possible to reproduce slow and still-motion pictures, and to set a reproductive slow-motion ratio by using an electromechanical converter which is able to move perpendicularly to the scanning direction of a rotary magnetic head.
CONSTITUTION: This reproducer is equipped with electromechanical converters 7 and 8 which can move perpendicularly to the scanning direction of rotary magnetic heads 9 and 10, magnetic-tape speed control method 38, clock signal generator 54, counters 49 and 55, and D/A converters 51 and 57. During reproducing, the speed of magnetic tape 2 is reduced by method 38 to 1/n as low as that during normal reproducing corresponding to a slow-motion ratio of 1/n and when the clock at the still-reproducing time is (fs), the clock at the slow-reproducing time is supplied to counter 55 at (fs). Then, its output is supplied to D/A converter 57 to obtain a saw-tooth signal, which is applied to converters 7 and 8, thereby making heads 9 and 10 scan on recording tracks accurately.
