Research firm TrendFocus sees hard drive shipments to consumer electronics makers soaring to 55 million units in 2006 from an estimated 17 million this year. Blazing a trail for the market is Japan’s Toshiba, which provides small drives for Apple Computer’s hugely popular iPod music player. Toshiba controls 98% of the market for the 1.8 inch-diameter drives used in the iPod, which can pack up to 10,000 songs in a device the size of a deck of cards, and its small drives are also appearing in a miniature video camera that can record up to two hours of high-definition video.
