<p>The present invention relates to an optical disk drive comprising an actuator assembly (10) having a first portion (412) and a second portion (414) being pivotally mounted to a shaft for positioning the second end relative to the surface of the disk, the second portion comprising a plurality of a planar elements, and an optical pick up unit acting focus a light beam on an optical disk. The second portion may comprise at least three planar elements, and may include fibres selected from the group comprising carbon, magnesium, borom, berryllium, Kevlar, glass and ceramic. This ensures a high stiffness tiweight ratio.</p> |
