<p>A carrier device (300) for supporting disc shaped articles D such as data carriers during production processes comprises a metallic support frame (301) and side rails (302) of a plastics material. The rails (302) have hook-shaped elements (321) for engagement with lower longitudinal frame members (312) of the support frame (301). The rails (302) also have lower lugs (325), which slot into receivers (326) on base supports (315,516) on assembly. The assembly of the rails (302) to the support frame facilitates any expansion and contraction of the rails relative to the support frame during processing of the discs.</p>
