Inventor: SASAKI OSAMU
IPC: G11B7/26
Filed: 1986-03-18
Abstract: PURPOSE:To smooth the rear surface of a stamper and to eliminate the need for polishing the rear surface by forming an electroformed nickel film in a nickel sulfamate bath contg. an azodisulfonic acid. CONSTITUTION:The azodisulfonic acid is added to the plating bath 5 essentially consisting of the nickel sulfamate. A master disk 1 formed by vapor deposition of gold on, for example, a pattern surface, is attached to a rotary cathode 2 and is subjected to nickel plating in an electrodeposition cell 4 contg. the plating bath 5 with a case contg. granular nickel as an anode 3. The electroformed film is thereafter stripped from the master disk 1 and the master stamper stuck with the gold on the surface is produced. The stamper having the smooth and glossy rear surface is obtd. and the need for polishing the rear surface is eliminated according to the above-mentioned method and therefore, the production stage is simplified.
