摘要： A disk drive includes a disk that has a data side and an unread side. A first read head faces and is adjacent the data side. The disk drive also includes a cylindrical shroud wall that is substantially orthogonal to the unread side and that completely encircles the disk outer periphery. A radial spacing between the cylindrical shroud wall and the disk outer periphery nowhere exceeds 1 mm. The disk drive does not include any read head that faces and is disposed adjacent the unread side.
