The Effect of Incubation on the Performance of Laminated-Disk Assemblies

The effect of incubation on optical disk assemblies consisting of an infrared-sensitive organic recording layer spin-coated onto a smoothed and metallized glass substrate was discussed at the SPIE meeting in Arlington, Virginia. Excellent recorded information stability and recordability were reported for these disks after eight weeks at various incubation conditions. The configuration of the laminated disk assembly (LDA) was also discussed at that meeting; it consists of a coated plastic recording sheet laminated with an adhesive to a rigid aluminum substrate. In this summary, the effects of sixteen weeks of incubation at various temperature/humidity conditions on the performance characteristics of LDA's are discussed. Thirty-two week performance data will be presented at the April 1984 Topical Meeting on Optical Data Storage. The incubation conditions are listed in Table I.
