- Adjustment Of The Magnetic Head Position Track Following On Tapes (AREA)
Abstract
PURPOSE: To make it possible to reproduce signals without noise with scanning correctly recording tracks in an arbitrary reproducing speed, by moving the head in the rotation axis direction by using control signals from the tape and rotation position signals from the tape.
CONSTITUTION: A saw-tooth wave signal is formed in 21 by control signal PD which is reproduced from the tape by head 7, and signals PA and PB indicating rotation positions of rotary heads 1 and 2 are obtained by heads 5 and 6 to form sampling pulse PI. Then, saw-tooth wave signal SW is subjected to sampling by pulse PI, and rotary heads 1 and 2 are moved in the rotation axis direction by sampling hold voltage ES, and each head scans recording tracks on the tape correctly. Reproducing signals from each head are switched alternately in 26 by pulse PG from FF8 and are outputted as video signals through FM demodulator 29
