Panasonic manufactures BD-ROM Discs at its Panasonic Disc Manufacturing Corporation of America (PDMC) facilities in Torrance, California, U.S.A.
The production processes for the single-layer and dual-layer BD-ROM Discs produced using Panasonic's originally developed Spin Coating method are presented here.
 First, a substrate with a thickness of 1.1 mm is produced. |
 |
 The thickness is then unified at high speed, with nanometer precision. |
 |
| Separate from the substrate, a resin stamper is produced. |  |
The space layer is formed using the spin coating method, which uniformly applies a 25-micron layer of UV resin.| This is bonded to the L0 recorded layer. |  |
| Then, the resin stamper is separated. |  |
| Sputtering (Forming a new recorded layer: L1 recorded layer.) |  |
 The spin coating method applies a film with high uniformity from the center of the disc to the outer edge.  |
  |
 A 2-micron-thick film is formed by the spin coating method. |
  |
 After it is inspected for quality, the BD-ROM Disc is completed.  |
