Abstract
PURPOSE: To make it possible to obtain sufficient leaked magnetic flux in an air gap erasing head in spite of minutualized device and reduce its price by setting a specific energizing portion, which a required current passes through, on the tape- facing surface of a core portion.
CONSTITUTION: Slit part 4 extending to the width direction of magnetic tape 3 is set on front surface 11 forming a tape-facing surface in block-shape core part 1 from upper surface 12 to lower surface 13 in order to erase the track of a lower half of the width of tape 3. Energizing portion 6 consisting of materials with a high conductivity is inserted into slit part 4, and guide parts 7 and 7' formed by bending approximately in a U-shape are projected a little from back surface 14 along upper surface 12 and lower surface 13 and connected to current supply source 8. Tape contact part 9 is fixed on the upper portion of core part 1 and front surface 91 of contact part 9 forms tape-facing surface together with front surface 11. Moreover, a notch part for guiding guide part 7 is attached to a part of the lower surface.
