Abstract
A disk drive comprises a recording medium, spinning means, a head supporting device having a support arm disposed in a rotatable manner about a bearing unit in a radial direction as well as a perpendicular direction to a writing surface of the recording medium, and rotating means for rotating the support arm in the radial direction of the recording medium. A shape of the housing is defined based on a first straight line tangent to both an outermost rim of the rotating means and an outer periphery of the recording medium, and according to a quadrilateral comprised of the first straight line, a second straight line tangent to the outer periphery of the recording medium and perpendicular to the first straight line, a third straight line tangent to the outermost rim of the rotating means and perpendicular to the first straight line, and a fourth straight line tangent to the outer periphery of the recording medium and parallel with the first straight line, thereby realizing the disk drive that is compatible in external size with memory cards.
