| 61 | Process for producing a stamper for videodisc purposes | US944499 | 1978-09-21 | US4211617A | 1980-07-08 | Csaba K. Hunyar |
| A stamper for producing replicas of a video disc master formed of a glass substrate containing surface irregularities in the form of an information pattern of raised protrusions is formed by applying a strike coating of a conductive metal such as silver and then electroplating copper and nickel to form a self-supporting negative replica member, termed as "mother," which can be stripped from the surface of the master. The interior of the mother is cleaned and passivated preparatory to use as a mandrel in the electroforming of a positive replica submaster. The submaster may function as a stamper or be utilized after passivation as a mandrel in the electroforming of a submother from which a stamper or a plurality of stampers are formed. | ||||||

| In a record disk having a spiral groove in a surface thereof with the depth of the groove varying along the latter for representing recorded information, such as video signals; the groove has an inverted bell-shaped cross-section which is symmetrical about the median of the groove with each of the opposite side surfaces of the groove, at any location therealong, being defined approximately by the equationd.sub.x =d.sub.o .multidot.exp [-(x/w).sup.2 ]in which d.sub.o is the depth of the groove at the median thereof, w is the distance from the median of the groove to the point at the side surface of the groove where the depth is d.sub.o /e (e being the base of the natural logarithm), and d.sub.x is the depth of the groove at the respective side surface at a distance x from the median. The foregoing record disk is conveniently molded in correspondence with an original recording disk produced by directing a laser light beam which has a Gaussian energy distribution thereacross against a layer of positive type photo-resist material on the original recording disk while the latter and the light beam are moved relative to each other for scanning a spiral track of constant pitch on the original recording disk and while the intensity of the laser light beam is modulated by the information signals to be recorded, and then developing the layer of photo-resist material. | ||||||
| 63 | Method for making video discs and video disc molds | US753184 | 1976-12-22 | US4130620A | 1978-12-19 | Manfred H. Jarsen |
| A matrix is used to prepare a mold of an elastomeric material. A polymerizable compound is coated onto a flexible, thin substrate such as Mylar and is placed with compound side in intimate contact with the mold. The compound is cured and is bonded to the substrate. The cured combination is stripped from the mold and is given a metallic coating to improve reflectivity. A clear plastic coating may be applied to protect the metal surface. | ||||||

| A method of forming a recording disc having a smooth groove suitable for recording video information from a disc having irregularities along the peaks between adjacent groove convolutions by replicating the grooved disc to produce a negative reproduction of the groove and applying an excess of deformable or removable material such as electron beam sensitive material to the surface of the replicated disc while rotating the disc rapidly only long enough to drive off the excess material and allowing the remaining material to dry, partially filling the groove and providing a continuous coating over the wall and valley portions thereof. | ||||||
| 65 | Method and system for the production of sheet or platter shaped information carriers | US682451 | 1976-05-03 | US4112030A | 1978-09-05 | Martin Kremzow |
| A method is provided for the production of sheet or platter shaped information carriers or records having surface structures thereon which correspond to recorded information, in particular video-signal memories of high storage capacity. An original or master information carrier or record has originally recorded information formed as a surface structure. This original is used to produce duplicate sheet or platter shaped records by applying a lacquer layer to the surface structure of the master record, hardening the layer, and permitting the hardened layer to adhere to an unmarked surface on the duplicate record to be produced. | ||||||

| 69 | Duplicating process for video disc records | US3687664D | 1968-07-24 | US3687664A | 1972-08-29 | BROADBENT KENT D |
| A DUPLICATING PROCESS FOR FORMING DISC RECORDS BEARING OPTICAL RECORDINGS REPRESENTATIVE OF VIDEO SIGNALS IS PROVIDED. A TRANSPARENT DISC, FORMED FOR EXAMPLE OF PLASTIC OR GLASS, HAS A SURFACE COATED WITH AN APPROPRIATE OPAQUE MATERIAL, SUCH AS COPPER. THE SURFACE IS THEN EXPOSED TO A MONOMER VAPOR, FOR EXAMPLE, WHICH IS SELECTIVELY POLYMERIZED BY ELECTROMAGNETIC RADIATION, SUCH AS X-RAYS OR ULTRAVIOLET RAYS, ETC., THROUGH A NEGATIVE OF THE DESIRED VIDEO RECORDINGS. THIS RESULTS IN THE POLYMERIZATION ON THE COATED SURFACE OF THE DISC OF A HYDROCARBON LAYER IN THE PATTERN OF THE VIDEO RECORDINGS OF THE NEGATIVE. THE PORTIONS OF THE COATED SURFACE WHICH ARE NOT COVERED BY THE HYDROCARBON LAYTER ARE THEN ETCHED OFF BY A SUITABLE ETCHANT, SUCH AS CHLORINE GAS, TO PROVIDE A TRANSPARENT PATTERN OF HOLES IN THE OPAQUE COATING WHICH ARE REPRESENTATIVE OF THE VIDEO RECORDINGS.

| Fabrication of an MO disc, the formation of a master pattern of servo and track information, and the subsequent transfer of that pattern to a series of pits and grooves on a substrate. On top of that substrate, at least one sacrificial layer is provided atop a relatively hard layer. The recording stack may be provided with both silicon nitride and silicon dioxide top layers, with the silicon dioxide layer acting as a sacrificial layer to ensure that the hard layer, of silicon nitride, remains at the end of the process. A layer of aluminum or aluminum alloy may be deposited, with the aluminum plugs filling the grooves and pits (created by the embossed servo information) to a level higher than any of the adjacent layers of silicon dioxide, silicon nitride, or similar dielectric layer. Since the polishing rate of aluminum can be far faster than that of the silicon dioxide, then the aluminum can be etched or otherwise removed down to a level equal to or slightly below a planar surface with the silicon dioxide, with the silicon dioxide layer allowing for some small level of over polishing. The silicon nitride layer is protected completely; the silicon dioxide layer partially remains and is partially removed; and the aluminum metal which fills the grooves and pits would rise only to a level substantially equal the very flat top surface of the silicon dioxide. | ||||||
