Seagate, well known as a leading hard-disk manufacturer for computers, will introduce 1-inch disk drives in capacities of 2.5 gigabytes and 5 gigabytes for use in portable music or video player and handheld computers as well as a compact flash card format for digital cameras and a USB pocketable external drive. The only major supplier of 1 inch disk drives has been Hitachi Global Storage Technologies who couldn't keep up with demand for its largest capacity 4-gigabyte Microdrive used in the popular Apple iPod Mini music player and its rival, the Creative MuVo 2. The new 1-inch products will be available in the third quarter as part of Seagate's largest ever product portfolio expansion, the company said. Expexted pricing for the 5-gigabyte compact flash card and USB external drive will each cost less than $200.
