After two false starts, dogged Control Data Corp is trying again to get it right in the 3.5 Winchester business, and a design team from its Magnetic Peripherals Inc unit has been transferred to Simi Valley, California to develop drives in the 40Mb to 80Mb capacity range. It hopes to have a product by the end of the year, and will make the drives either at the Magnetic Peripherals plant in Oklahoma, or at an offshore location in the Far East.
