A manufacturing process for a light-sensitive material having thereon a magnetic recording layer, the magnetic recording layer having excellent optical transparency, a high magnetic recording performance (S/N ratio) and good graininess. After applying a coating solution on a support, the coating solution containing a magnetic substance, the support is dried while it is passed through an orienting magnetic field to orient the magnetic substance contained in the coating solution in a fixed direction.

Silver halide photographic material and a manufacturing method therefor

Disclosed is a silver halide photographic material comprising a silver halide emulsion layer on at least one side of a support and at least one magnetic recording layer on at least one side of the support, and the magnetic recording layer is transparent and comprises a ferromagnetic powder, a silica and alumina co-precipitate on the surface of the ferromagnetic powder, and a binder.
