SAN FRANCISCO — An increasing number of computer users will have the capability to record their own compact discs and, eventually, digital versatile discs. Bayer AG's plastics division in Leverkusen, Germany, is researching next-generation resins to serve that market.
``There is a move to replace magnetic storage media such as floppy discs,'' Hartmut Lower, industry manager for optical storage systems, said at Replitech in San Francisco. With less-expensive computer drives, recordable CD production is more than doubling every year.
In contrast, he said demand for CD audio is slowing down or even declining.
Bayer is working on products with shorter wavelengths, closer track pitches and improvements in molding windows, bi-refringence and replication, said Ramesh Pisipati, industry manager for optical memory with Bayer Corp.'s plastics division in Pittsburgh.
