Toshiba is expected to sell the tiny drive later this year.
TOKYO, Japan (Reuters) -- Japan's Toshiba Corp said on Tuesday that Guinness World Records had certified its stamp-sized hard disk drives (HDDs) as the smallest in the world.
The electronics conglomerate's 0.85-inch HDDs, unveiled in January, have storage capacity of up to four gigabytes and will be used in products such as cell phones and digital camcorders.
Toshiba, whose 1.8-inch HDDs are used in Apple Computer Inc's hot-selling iPod digital music players, for example, aims to start producing the 0.85-inch HDDs by the end of 2004.
"Toshiba's innovation means that I could soon hold more information in my watch than I could on my desktop computer just a few years ago," said David Hawksett, science and technology editor at Guinness World Records.
