IBM has recently announced a hard disk drive with a disk platter about the size of a large coin.
The Microdrive, which at 20 grams weighs less than an AA battery and can hold around 200 times more data than a floppy disk, is aimed for use in portable electronic devices including digital cameras and handheld PCs, according to IBM.
The Microdrive uses hard disk drive technology to store information, unlike other portable storage options such as flash memory, the company said. The cost per megabyte for the Microdrive is thus much less than for other portable storage options, according to the company.
The 340MB Microdrive fits in to a CompactFlash Type II slot and will be available in mid-1999, a spokesperson for IBM said.
