An Optical disc stamper uses a red or blue laser to record and read data. The majority of optical disks on the market today are flat, round, and 12 centimeters in diameter. The data is stored on the disk as nanoscale data pits and lands. The pits are engraved into a recording material's reflective layer. The lands are the flat, undulating landscapes that surround the pits. The sort of material utilized for the recording is determined by how the disk will be used. https://discheminc.com/nickel-sulfamate-electronics-electroforming/
