Title:
MAGNETIC RECORDING AND REPRODUCING METHOD
Document Type and Number:
Japanese Patent JPS60185211
Kind Code:
A
Abstract:

PURPOSE: To record and reproduce many kinds of video signals simultaneously and efficiently by additionally inserting another magnetized locus into a guard band generated by increasing a tape travelling speed in parallel so that the guard band is left.

CONSTITUTION: Since magnetic heads A1, B1 having head width wider than the width of a track to be reproduced are used, close recording between adjacent tracks due to superposed recording is performed. Since a reproduced output is not changed even if tracking is shifted within the difference between the head width and track width, an objective channel can be easily selected and reproduced. To reproduce video signals on an adjacent track and the track next to said adjacent track, its channel can be selected by shifting the relative positions between the magnetized locus and the magnetic head by one/two tracks.
