Abstract

1,250,967. Magnetic recording medium. AGFA-GEVAERT A.G. 15 Dec., 1969 [17 Dec., 1968], No. 60971/69. Heading H1H. [Also in Division B6] A symmetrizing magnetic tape is made by printing parallel strips, of uniform width and spacing, of a magnetic suspension on to a carrier tape, using a printing cylinder in a rotary printing method. In Fig. 1 (not shown), magnetic suspension 2 in trough 1 is uniformly coated on to dipping cylinder 3 using doctor blade 5 and is transferred firstly to a toothed printing cylinder 6 rotating in close proximity (e.g. 0À1 mm.) to cylinder 3, and thence to carrier tape 8 on coacting cylinder 9. In one embodiment, the peripheral speed of printing cylinder 6 is greater than the running speed of carrier tape 8, in order to avoid build-up of magnetic solution on the rear edge of the strip, caused by the suction effect of the printing cylinder.
