Method of manufactureing a record matrix |
| abstract |
In manufacturing a record matrix from a lacquer master having a sound groove in a surface thereof, a basic reduction solution containing borohydride compound and an acidic metal salt solution containing nickel salt, ammonium salt and lactic acid are sprayed against the surface of the master having the sound groove for effecting the electroless plating thereon of a nickel surface metal layer having thereon a projection strip coincident with the sound groove, a reinforcing layer is formed over the surface metal layer and its reinforcing layer are peeled off from the lacquer master along the boundary therebetween to provide the record matrix. |
