Abstract
A method for large scale and economical manufacture of a second surface optical recording disk is disclosed. An optically transparent disk cover with tracking grooves and data etched on a mating side thereof is mated and embossed into an optically reactive layer of a first surface optical recording laminate web or sheet having an optically active layer, a reflective layer and a web support layer. The second surface optical recording device thereby created is then cut from the laminate web to yield a very inexpensive second surface optical recording disk.
