Daewoo bought a stake in Corona Data Systems.

The Thousand Oaks-based maker of personal computers, printers and related products said it received more than $20 million from Daewoo Group, a Korean conglomerate that manufactures some of Corona’s equipment. Corona, which has long sought new financing, did not disclose how much of a stake it sold to Daewoo. Corona also said it will change its name in January to Cordata to help overcome its image as an IBM “PC clone” manufacturer.
