Optical sector firms must expand to survive, CMC's head says

Some of Taiwan's top optical drive manufacturers concentrate on R&D and subcontract production to electronics manufacturing services companies.

Taiwanese manufacturers expect the monthly output of optical drives to increase by an average 27 percent this year. DVD drives account for more than half of suppliers' output, a trend that is expected to intensify this year. DVD dual drives, at the top of the line, account for 18 percent of total output.
