Abstract

A suspension arm (125) for a head (120) of a disk storage device comprises at least one wall (225, 230) substantially perpendicular to the disk (105) and having a portion (238, 239) which is deformable parallel to a plane extending through a longitudinal axis (235) of the suspension arm (125) and perpendicular to the at least one wall (225, 230), and piezoelectric member (240, 255) which can deform the portion (238, 239) in order correspondingly to move the head (120), the piezoelectric member (240-255) being fixed to the portion (238, 239) of the at least one wall (225, 230).
