Abstract

PURPOSE: To improve orientation characteristic and audio output over the entire layer of a video tape by coating a magnetic coating liquid on a substrate while applying magnetic field across the free falling curtain of said magnetic coating a strongly magnetic metal and a binder is fed throubh nozzle 1 and pipe 2 to pocket 4 of cating head 3 and, with ensured dyanamic pressure being cancelled, further permitted to flow down from slit 5 to form a free falling curtain 6. A magnetic field is applied by air-core solenoid coil in the falling direction, and the curtain 6 thereby oriented form magnetic layer 10 on a bandshaped substrate. Air shield 11 is provided for the purpose of removing air accompanied with substrate 9 to keep curtain 6 stabilized. The substrate 9 for carrying layer 10 thereon, while it is supported on a backing roll 12 and auxiliarily oriented by magnet 13, if desired, is then conveyed to drying step.
