Filed: 1984-07-16
Abstract: PURPOSE:To reduce the feed amount with a small erasion nozzle by producing a saturated magnetic field and unsaturated magnetic field with two DC erasion heads and erasing the remaining magnetic fields with an AC erasion head. CONSTITUTION:The magnetic flux density corresponding to a point (b) where a saturated magnetic field is produced by a contact with a DC erasion head 3 when a magnetic layer 2 of a magnetic tape 1 having contacts with three erasion heads has the remaining magnetic flux density equivalent to a point (a). Then the density (c) is obtained at zero of magnetic field intensity in the driving direction A of a tape. Then a DC erasion head 4 produces anxunsaturated magnetic field of the opposite direction and then the minute remaining magnetic flux density with density (d) and zero magnetic field intensity secured at a point (e). Finally the layer 2 has a contact with an AC erasion head 5 to produce a faint alternating magnetic field. Thus the remaining density is approximately equal to zero. This reduces the feed amount to the head 5 and also the flowing current amount. Thus the degaussing is possible at a high speed with a high degaussing frequency.
