Abstract
PURPOSE: To make it possible to select the magnetic track by using a sheet of magnetic plate or magnetic cylinder, whose surface has been magnetically coated, by writing and reading after depressing the magnetic head and scanning, and by dividing the recording medium and locating it.
CONSTITUTION: The magnetic drum 13 is a round bar consisting of non-magnetic material, its surface has the recording face to which magnetic thin film is coated, and the track is selected manually by mounting the rotary division locating device of this drum 13. On the other hand, the DC motor 25 is connected to the feed screw 28 through the reduction gears 26, 27. Installed to the feed screw 28 is the screw groove 281, both the ends are supported with the bearings 282 of the frames 11 and 12, respectively, to one end of the head holder 29 is installed the magnetic head 20, the gap part is lightly pressed down to the surface of the magnetic drum 13 with the plate spring 21, and it is made to contact by pressure suitalbe for writing and reading. Mounted to the frames of both sides are one pair of light detectors 22 and 24, and when the tip part of the plate spring 21 has gone into the slip part 23, it can be detected optically.
