Abstract
The invention may be embodied in a disk drive for use in a mobile device. The mobile device may be a hand held computing device such as a personal digital assistant (PDA) or a mobile terminal such as a cellular telephone. The mobile device includes a host processor for accessing data on the disk drive. The disk drive has a rotating disk media surface and a moveable read/write head disposed over the media surface. The disk drive includes a first data storage zone on the disk media surface for storing data on first data tracks using a first track pitch, and a second data storage zone on the common disk media surface for storing data on second data tracks using a second data track pitch. The first data track pitch is substantially wider than the second data track pitch.
