Tandon and TEAC settled a patent suit.

TEAC agreed to pay Tandon an undisclosed sum plus royalties on future sales of TEAC 5-inch double-sided floppy disk drives, the companies reported jointly. Chatsworth-based Tandon also agreed to drop a federal lawsuit and a patent infringement claim before the U.S. International Trade Commission. Tandon earlier settled a similar dispute with Sony but is still pressing its case against Mitsubishi. Tandon claims that the Japanese companies used its patented disk drive technology without permission.
