Toshiba has won a Guiness World Record with its 0.85-inch hard disk drives, Reuters reports.

The new tiny hard drives were announced in January and offer up to 4GB storage. Toshiba expects to see the products used in such devices as mobile phones and digital camcorders.

David Hawksett, science and technology editor at Guinness World Records said: "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."

Toshiba products are already employed in Apple's iPod products (though iPod mini uses hard drives from Hitachi). The company plans to start volume manufacturing of its award-winning tiny hard drives by the end of 2004.
