    • 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.
    • 磁盘驱动器包括记录介质,旋转装置,头部支撑装置,其具有以径向方向围绕轴承单元可旋转地设置的支撑臂以及与记录介质的书写表面垂直的方向,旋转装置 用于沿着记录介质的径向旋转支撑臂。 壳体的形状基于与旋转装置的最外边缘和记录介质的外周两者切线的第一直线来定义,并且根据由第一直线组成的四边形,第二直线与 记录介质的外周并且垂直于第一直线,与旋转装置的最外边缘相切并且垂直于第一直线的第三直线和与记录介质的外周相切的第四直线 并与第一直线平行,从而实现与存储卡兼容的外部尺寸的磁盘驱动器。
