Samsung group has Samsung Electric and Samsung Electronics. As is well known, they produce lots of things and aim to produce most of the key components inside the group. Toshiba does help as well. The DigiTimes article is clearly wrong about the top five ODD makers. NEC and Pioneer are strong in DVD writers, but not in CD-ROM, CD writer, combo drives. TSST has 2 billion USD market share. Both in terms of revenues adn number of units, TSST is No. 2 after HLDS. Samsung one billion and Toshiba another billion, to say it roughly. Samsung makes far more ODD units but the average unit price of Toshiba is far higher.
